Sandhya, Sandhyamsa and the entry of Kali in Dharma Yuga scale. (Supplement to Mahabharata date series - 7)

 Previous

Next

Recap:

·         The 5-year Yuga was conceived sometime after the episode of Mārtanda, the blurred sun of the Younger Dryas period the ended c. 11,700 BCE. The conjunction of the sun and the moon at the beginning of Uttarayana marked the first year of the 5 year Yuga.

·         The Catur Maha Yuga running into lakhs of years was conceived after Saturn was discovered in the Younger Dryas period. After the discovery of all the nine planets (that include the sun and the moon and the nodal points of the moon), the orbital cycles were observed and calculated that facilitated the computation of the conjunction of the all of them at one point of the zodiac. This is found to happen at the beginning of Aries every 4,32,000 years. That conjunction was due after the Mahabharata war.

With this background, let me focus on three features that are needed to be known.

The first is about the names of the four Yugas, the second about Sandhya and Sandhyamsa period and third on the mathematic validation of the Kali Yuga. The first two features are explained in this part while the third will be given in the next part that would further establish how the Aihole inscription must be read.

To understand any concept, the name-form and works must be analyzed for they are integral to each other, says Chandogya Upanishad.[1] The names of the Yugas, Krita / Satya, Treta and Kali must be understood in that way. These names have appeared in contexts other than the Yugas. In Taittriya Samhita they appear with meanings - path, moving, leading and as carrier. While placing the layers of bricks for the yajna kunda, Krutamayānām is in the East, Tretāyānām is in the South, Dvāparoyānām is in the West, but instead of Kali, it is Askandoyānām in the north. Askanda has many meanings, including attack and ascending. The verse further goes on to name the zenith as Abhibhu which means both superior and suppressor. This naming appears to represent counting and also the movement. As such these names became the natural choice to indicate the movement of Time as Yuga.

Counting associated with the four names Krita, Treta, Dvapara and Kali appear in the dice game too. They represent the numbers 4, 3, 2 and 1 respectively form Krita onwards. The die having one dot on its side is Kali, two dots are for Dvapara, three dots represent Treta and four dots are known as Krita. Krita (4 dots) means winning and Kali represents loss. Tough these names were meant to be numbers; specific characterization is associated with them.

Such characterization is used to describe personalities, such as Duryodhana as having born of Kali and Shakuni of Dvapara. Shakuni attained the realm of Dvapara after his death. Such characterization is used to describe the nature of times too. Before leaving Hastinapur after the failed peace mission, Krishna kept repeating to Karna that there would not be Krita or Treta or Dvapara but only Kali Yuga when the Pandava brothers destroy the Kauravas.[2]

Wars had taken place many times in the life time of Krishna and Karna but we never came across any mention of Kali then. Krishna’s rise to popularity started with his slaying of his uncle Kamsa, but none said there was Kali then. Krishna himself was targeted by the Pandya king who wanted to avenge Krishna for having killed his father. There was no talk of Kali then. But in the big war of the cousins, Kali’s furious dance was expected to be seen because the war was not just for the land but for honor, for restoration of honor and revenging for the humiliation meted out to Draupadi more than the Pandavas themselves. So the display of extreme Krodha was expected then. Krishna forewarned it to Karna when the war was certain, and expressed the same when Duryodhana was given a fitting reply by Bhima for what he did to Draupadi. In the absence of corroborative support from the presence of Kali Yuga of the Catur Maha Yuga system at that time, one cannot assume that Kali Yuga started then.

By the mention of Krita and Treta -in the Yuga of Dvapara, Krishna had also indicated that there were times of Krita and Treta even within Dvapara Yuga as these are all about presence of certain characteristics of those Yugas for some time. In this way certain instances have been recounted by the sages on the presence of Krita and Kali Yuga in Treta Yuga and Treta in Dvapara Yuga.

The chastisement of the King also determines the nature of the Yuga. Many instances are given in Mahabharata in support this. Even in the Vaiṣṇavite literature, the Alwars who lived in the period of Pallavas in the Common Era were pronounced as having lived in Dvapara Yuga though Kali Yuga was running then. (Written by me HERE) All these imply that one needs to do contextual reading to understand what is being said.

Yuga Sandhi and Sandhyamsa

The second feature I want to highlight is about Sandhya and Sandhyamsa of the Yugas. Manu being earliest in chronology, his version can be taken as the early Thought on the Yugas. His version of duration of 4000, 3000, 2000 and 1000 divine years (1 divine year = 360 solar years) respectively for Krita, Treta, Dvapara and Kali is found in almost all the literature on Yuga. However his reference to Sandhya (twilight) period is not unanimously echoed in other texts. He added Sandhya period before and after a Yuga. [3]

             Yugas with Sandhya period (in Divine years)

This is markedly different from the Puranic version.

The Puranas give a more detailed classification for each Yuga. According to them there are two - Sandhya and Sandhyamsa - both of them occurring one after the other at the end of a major Yuga. The Sandhya being evening time, it represents the time coming after the Yuga and not before.

Let me begin from the six features of the Yuga given in the Puranas. The following is told by Vayu Purana. [4]

A similar version is given by Brahmanda Purana as follows:[5]

Six features appear in both these Puranas.

1.      Yuga

2.      The difference of Yugas

3.      Yuga Dharma

4.      Yuga Sandhi

5.      Yugamsaka or Sandhyamsa

6.      Yuga Sandhana

There is no difficulty in understanding Yuga and the difference of Yugas.

But Yuga Dharma is unique for each Yuga. It is basically formed by the dominance of a Guna. Sattva Guna is dominant in Krita, Rajasa in Treta, a mix of Rajasa and  Tamasa in Dvapara and only Tamasa in Kali Yuga.[6]

The Dharma - adharma  proportion of the Yugas are given as follows.

Krita  -  1 part dharma - 0 adharma

Treta - 3/4 part dharma - 1/4 adharma

Dvapara - 1/2 dharma - 1/2 adharma

Kali - 1/4 dharma - 3/4 adharma

Thus the decline in dharma factor leads to a change in the Yugas.

Towards the end of a Yuga, its Yuga Sandhi appears.

The Sandhyamsa comes up after the Sandhi period ends.

Then the next Yuga takes over.

The Puranas differ from Manu in the placement of the sandhi period as follows:

The Sandhya period is followed by Sandhyamsa which means ‘part of Sandhya’. The dharma of a Yuga dwindles by 3/4th in the Sandhya of that Yuga. In other words, only 1/4of the Dharma of a Yuga prevails in the Sandhya period. The reduced Dharma of the Sandhya period gets further lessened by 3/4th in the Sandhyamsa period. This remnant part of Dharma of the Sandhyamsa period becomes the Dharma of the next Yuga. The Brahmanda Purana version is given below: [7]

The Vayu Purana version is reproduced below:[8]

Brahmanda Purana tells how the residual Dharma of the Sandhyamsa of a previous Yuga becomes the Dharma of the next Yuga.[9]

This can be expressed as follows:

Krita Yuga – Dharma 1 part

Krita Sandhya – ¼ dharma

Krita Sandhyamsa  = ¼ of ¼ = 1/16

1/16th of Krita Yuga Dharma becomes the Dharma of Treta Yuga.

Since Treta Yuga has 3/4th Dharma and 1/4th Adharma, the Dharma portion is equal to only 1/16th of the Krita Yuga Dharma.

In Treta Sandhya this Dharma further gets reduced to 1/4th

 = 1/4 of 1/16 of Krita Yuga Dharma = 1/ 64.

Treta Sandhyamsa = ¼ of 1/64 = 1/256

At the end of Treta Yuga only 1/256 Dharma of Krita Yuga remains.

This becomes the amount of Dharma in Dvapara Yuga which has ½ Dharma and ½ Adharma

By continuing in terms of the remnant Krita Dharma,

Dvapara Sandhya = ¼ of 1/256 Dharma = 1/1024

Dvapara Sandhyamsa = ¼ of 1/1024 = 1/4096

The Mahabharata war occurred in Dwapara sandhi when there was 1/1024th of Krita Yuga Dharma was present.

Now we will take up only the portion of dharma of Dvapara Yuga for easy understanding of the verses of Mahabharata.

In terms of Dvapara Dharma ( ½ Dharma and ½ Adharma )

¼ of ½ Dharma of Dvapara prevailed at Dvapara Sandhya = 1/8 parts

When the prevailing Dvapara Dharma was perceived to have dwindled to 1/8th, it was a warning bell that Kali Yuga was nearing.

The war of Mahabharata was fought in the Sandhya period of Dvapara. 1/8th Dvapara Yuga Dharma was prevailing then. Many transgressions occurred in that war for the first time in the known history of the people of Dvapara. When Bhima hit Duryodhana below his waist against the norms of the mace fight, Krishna exclaimed, “prāptaṃ kaliyugaṃ viddhi[10]

{Prāptā = attained to, reached to.

Viddhi = the act of piercing, perforating (second person singular present imperative class 2 parasmaipada √vid)}

This doesn't mean that Kali Yuga had arrived. That being the Sandhya period, 1/8th of Dvapara Dharma was still prevalent. The transition is yet to happen to Sandhyamsa and then only to Kali Yuga. The drop in the Sandhya Dharma by three-fourth signals the arrival of Sandhyamsa when 1/32 part of dvapara dharma would remain (1/4 of 1/8). The Sandhyamsa must go on with quarter of Sandhya Dharma steadily for some time. Then only the complete transition to Kali Yuga can take place.

With Sandhyamsa yet to come, the Praptam Kali Yugam verse by Krishna did not mean the arrival of Kali Yuga.

This kind Sandhi was reported earlier between Treta and Dvapara when Parashurama killed many Kshatriyas. The same location, Samanta Pancaka hosted the river of blood in that sandhi, says Mahabharata. [11] The carnage unleashed by Parashurama was of a nature heavily loaded with Tamasa also in addition to Rajasa which was a prominent trait in Treta Yuga. This was followed by Treta Sandhyamsa and then Dvapara Yuga having a mix of both Rajasa and Tamasa.

The decline in the nature of Dharma had not followed any specific time period. This can be established from the verses of Srimad Bhagavatam.

Bhagavatam states in no uncertain terms that Kali entered only after Krishna left the earth.


This cut-off date marked by Krishna’s exit is repeated again in Srimad Bhagavatam.


The next verse also repeats this idea.

Now a crucial verse comes. The very next verse talks about the Saptarishis! The Saptarishis had laid down the rules of law and guided humanity as per the scriptures including the Puranas. The sages had a measure of unit to gauge the rise or decline of Dharma by a calculation of the movement of the Saptarishi Mandala in the sky. After having said that Kali Yuga started at the exit of Krishna, Bhagavatam says that Kali Yuga started at the time the Saptarishis were passing through the star Magha!

Similar reference to Saptarishis in Magha appears in Brihat Samhita that “The earth was controlled by the king Yudhishthira in his shaka kala of 2526 (years) (when) the Saptarṣis (muni) were in Maghā (star)” [12] This repetition shows that it was a cut-off date, 2526 years after Kali Yuga started at the exit of Krishna. The next verse gives further clarity by stating that Kali Yuga began from the time of Nanda Dynasty!

What is this Kali Yuga? Then what was that kali at 3101 BCE when Krishna left? Vyasa clarifies in the very next verse that, “ Those who scientifically understand the past declare that on the very day that Lord Sri Krishna departed for the spiritual world, the influence of the Age of Kali began.”

The word “Pura-vidah” is used to show the source from which this knowledge that Kali Yuga started only after Krishna left the world. Pura means olden, formerly, in the beginning. Vida means knowledge. So that Kali Yuga was the original cut-off date sanctioned by the sages soon after Krishna left. Once again Kali Yuga coming 2526 Years after the Kali Maha Yuga could only mean that it signaled the end of Sandhyamsa of Dvapara Yuga in DHARMA scale!

Certain texts coming up after this later date even state that Parikshit was the king then. It cannot be so. Janamejaya Pariskhita’s inscription at Kali 89 is proof of Parikshit having lived before that time. A combined reading of these two Kali Times given by same text emphasizing that Kali Yuga did start at the time of Krishna’s exit could only mean that there existed two different yardsticks for measuring the Yugas. One was the Catur Maha Yuga measured by planetary conjunction. The other was based on the nature of Dharma and the decline in its measure. The Saptarishis were taken as pointers for deciding the decline in Dharma.

Another major difference between these two Yuga scales is the absence of any specific time period for the Dharma based Yuga cycle (whereas the Catur Maha Yuga has fixed number of years computed on the basis of planetary movement)

In the many ways that I tried to figure out a rationale for the 2526 year period, I found that there was no pattern detectable. Perhaps Saptarishis in Magha, the star of Pitrus signaled the death of many in unfortunate ways and hence taken as a marker for Kali Yuga in terms of Dharma. That period (575 BCE) also coincided with the rise of Mleccha-hold in Bhartavarsha.

In 100 years from now the Saptarishis are going to cross the same star Magha! Whether we will be entering Kali Sandhya or Sandhyamsa or just further intensification of Kali is not known. What is known is that the Maha Yuga scale of the Yuga should not be confused with the Dharma based Yuga scale.

It is in the Dharma based Yuga scale of Treta Yuga Parashurama and Rama lived. It should not be confused with Treta Maha Yuga of lakhs of years.

It was on the basis of Dharma of the Dvapara Sandhya, Krishna said ‘Praptam Kali Yugam Viddhi’. It should not be assumed as the beginning of Kali Yuga. With scriptural evidence shown above for Kali Maha Yuga starting at the exit of Krishna and Kali Dharma Yuga starting only at 575 BCE, the planting of wrong information among the public on Kali Yuga date must stop. If it continues it is a case of Krishna dealing with people pressing them more and more in tandem with their nature. 

The discourse on this particular topic is not yet over. There is a clear cut time period from the start of Treta Yuga onwards in the Dharmic cycle, decipherable from the Puranas - concurring with the deduction done earlier on post -11,700 BCE for the genesis of the Yuga concepts. That will be discussed in the next part following which we will see mathematical proof for the Kali Maha Yuga that started with the exit of Krishna.

Yuga computation took place only after 11,700 BP (Supplement to Mahabharata date series -6)

 Previous

Next

There are several sources of information on Yuga of which the most important are the Puranas, the Jyothisha Siddhantas and Mahabharata. What we gather from these is applicable to different contexts of reference on Yuga in other sources. Therefore these three can be taken as the primary sources.

One of the five characteristics of a Purana is to give the details of Time at macro and micro level.[1] These are the foundational theories on Yugas. The Jyothisha Siddhantas are primarily about space and time, and calculation of time. Their authority is paramount of all the sources. Mahabharata has many instances of discussion on Yugas.

The foremost feature gathered from these sources on Yuga is the simultaneous use of two types of Yugas in the past. They are the 5 year Yuga and the Catur Maha Yuga having Krita, Treta, Dvapara and Kali Yuga divisions. Both share a common feature – Yugma or Yugya known as Yuga. Yugma means even. Yugya means yoked or fit to be yoked. There is some evenness and yoking nature in both the 5 year Yuga and the Catur Maha Yuga.

The 5-year Yuga

In this type of Yuga, Yugma (evenness) is attained by matching the sun and the moon. Due to the variations in the speed of these two planets, they do not meet at the same point of the zodiac at the same time every year. Such meeting can happen in the 6th year after expunging two lunar months (Adhika Masa). The five year period is evenly split in terms of stars and tithis in such a way that the initial conjunction of the sun and the moon in the first year is repeated again on the 6th year – which was recognized as a next Yuga of 5 years.  Using the inputs from Lagadha’s Vedanga Jyothisha, the 5 year Yuga calendar of the Mahabharata time was derived in Part 3 and is reproduced here.

Figure 40: The 5-year Yuga at the time of Mahabharata

The important feature of this Yuga is that Uttarayana served as the year beginning. The true position of the sun turning towards north was taken into reckoning in the 1st year. When the moon joined this sun, that day was the day of Uttarayana in the 1st year. Only the sun and the moon yoked the year (Yugya). There is no evenness attained with the planets. One must recall the previous part (Part 5) where I pointed out that Prof. Srinivasa Raghavan had erroneously assumed a congregation of all the planets at Uttarayana as a mark of the “Astronomical Yuga”. Readers must rest assured there is no such Astronomical Yuga starting at Uttarayana, mainly because there is no conjunction of the planets except the sun and the moon.

Another feature of this Yuga is that every 7th tithi and the 19th star at the time of Uttarayana in a year become the tithi and the star of the next ayana (Dakshinayana) of the year. This pattern repeats only in the 6th year, thereby bringing in the next Yuga. Based on the tithi and the star in a year, one cannot pick out the position of the sun as Prof. Raghavan had done. He zeroed in on the zodiacal degree by Magha Shukla Ashtami at 317 degrees. The moon would be at 90 degrees from the sun on Ashtami. So he added 90 degrees to that to get the vernal equinox. Moon at Rohini concurred with that, according to him.

If we use the same method for the third year of the 5 –year Yuga calendar on Mahabharata (Figure 30) it was waning Dasami on the day of Uttarayana and the moon was in the star Magha. Where would one get the sun’s position by Raghavan’s method for Uttarayana and the location of the vernal equinox from that?  For Magha Krishna Dasami, Uttarayana would begin at 334 degrees (317 added with 17 degrees for 17 days between Shukla Ashtami and Krishna Dasami). Ninety degrees from there the vernal equinox would occur at 64 degrees, i.e at Gemini 4 degrees! This is no way different from the use of the astronomy software to pick out the solstice and the equinox at tropical locations. The learning is that this Yuga cannot be arbitrarily used to locate the Uttarayana. Those wishing to see the display of this Yuga in planetariums, can never realize their wish because the Uttarayana position keeps shifting every year in this Yuga and no astronomy simulator is equipped with the settings needed for this since no ground work has gone into even understanding this knowledge of the Vedic seers. 

This 5-year Yuga is not a permanent one either, since the calendar shifts (or re-done) with the shift in the position of the solstice and the equinox. In an average of 66.66 years (Surya Siddhanta average), the sun’s equinoctial position shifts by a degree and with that a new date of conjunction with the moon comes into being. We don’t know how often they renewed the calendar – whether with every degree of displacement or once in a few centuries by adjusting the difference during the time in use, but this was used for all ritualistic and civil purposes. Based on this Yuga, Bhishma calculated that the Pandavas had spent additional days in exile.

This Yuga seems to have been used for calculating one’s life. From a reference in Rig Veda on the sage Dirghatamas that he grew old (or perished) in the 10th Yuga, it is understood that one’s age was expressed in terms of this Yuga.[2] Dirghatamas appearing before Ramayana times, it is understood that this 5-year Yuga was in vogue during Rama’s period. Any research on the date of Ramayana requires the 5 year Yuga calendar of that time as I did for Mahabharata. So far I have located just one hint in Valmiki Ramayana to zero in on the 5 year Yuga configuration of that time which I will work out in another context.

When did the 5-year Yuga begin?

Interestingly this Yuga scale offers a hint for its beginning time. That time is deduced from Mārtanda, the sun that was born as Vivasvan initially (the sun of the current times) but remained inside the egg. It represented a time of insolation after the last Ice Age ended some 13,000 years ago.[3] However after a brief period of insolation for 500 years a mini Ice age set in, due to a comet-fall. This period known as Younger Dryas had the sun looking obscure, dull and gloomy due to the dust particles in the air kicked off by the fallen fragments of the comet. The sun appeared as though it was still lying inside the cosmic egg. This Younger Dryas period lasted between 12,900 to 11,700 BP (BP= Before Present). Regular sunlight started falling on the earth only after this period. This is a scientifically accepted fact.

The obscure sun gained the name Mārtanda – because he was not dead (na mrta) though he was within the egg (Anda).[4]  It is also told in Rig Veda that Aditi, the mother of eight Suns brought Mārtanda to spring to life and die again.[5] With one less, she finally had seven suns of which the current sun Vivasvan is the 7th but the 8th son after Mārtanda. (Watch my video here). Once the sun became bright after the Younger Dryas, it became known as Vivasvan and from then onwards the Vaivasvata Manu period began. This was after 11,700 BP.

However Mārtanda was not forgotten. He was made the lord of the Adhika Masa! The Adhika Masa is nothing but a month that is very much present but remains dormant (not counted) much like Mārtanda. By assigning this month to Mārtanda, it is known that this 5-Year Yuga system that incorporates the Adhika Masa must have come into vogue only after the Younger Dryas, i.e. after 11,700 BP!

Dirghatamas and Rama had come up some time after this date.

The story of Mārtanda gives another hint that is of help to us in assigning the time period when the other Yuga scale (Catur Maha Yuga) was conceived. The hint was the birth of the planet Saturn!

The Catur Yuga system

The Catur Yuga system has the Yugma or evenness of all the planets (except Rahu, as one of the nodes would necessarily remain 180 degree away from the other). Jyothisha Siddhantas are the authority for this, in their goal of calculating the planetary orbital periods and their motion around the zodiac in geo-centric perspective. When all the planets joined together, it signaled the beginning of a Yuga.Gruha sāmānyam Yugam” says Aryabhatiya, referring to the super conjunction of planets marking a Yuga.[6] 

This requires the knowledge of all the planets by the time this Yuga system was conceived. Saturn being one among the nine planets of this system, the reference to the birth of Saturn (Sanaiscara) to Chāya and the dull sun Vivasvan (Mārtanda) of the Younger Dryas period, denotes the discovery of the planet Saturn during the gloomy period of Younger Dryas. Perhaps in the backdrop of faint looking stars of that time, the shift in the position of Saturn, that very much looks like a star, could have caught up the attention of the sky watching sages and thus was born the planet Sanaiscara.

A corroborative evidence for the date of this discovery in the mini ice period of Younger Dryas was the birth of two younger siblings to Sanaiscara. The youngest was Tapati, the river that flows down from the Satpura plateau in Madhya Pradesh. The name Tapati stems from ‘tapa’ - meaning warmth. Mul Tapi (Multai) from where it originates is only 2457 feet high, but it must have been snow covered during the Ice age to give rise to Tapati, once warmth descended on this region. (The Himalayas lying further north must have been heavily glaciated at that time, with Ganga still trapped within the Gangotri glacier. Any date for Ramayana before 11,700 BP is therefore absurd due to the absence of the River Ganga). With warmth spreading from the equatorial region to north at the end of the Younger Dryas, Tapati started flowing down. Before this happened, the planet Saturn was discovered.

The Catur Yuga system requiring the knowledge of all the planets, with Saturn being the outer most planet in Vedic astronomy, it must be understood that the conception of the Catur Maha Yuga could not have taken place any time before 11,700 BP. This is a crucial input considering the fact that this Yuga scale calculates 432,00,00,000 years (4.32 billion years) as a day of the Four-faced Brahma and 311,040 billion years as His age.

This calculation has the solar year as the basic unit. This being the year of the sun there can be no doubt about where it begins. Today it begins from Mesha / Aries; this was so in the past, as we had always followed the path laid by the sages. When all the planets except Rahu (ascending node of the moon) congregated at the beginning of Aries, Krita Yuga was born, says Aryabhatiya.[7] At the end of Krita Yuga, all the planets except Rahu congregated at the beginning of Aries, says Surya Siddhanta – by which we deduce that Treta Yuga started with this congregation at the beginning of Aries.[8] By calculating the subsequent beginnings, it is deduced that a similar congregation occurred at the beginning of Kali Yuga! (Read here).

This Kali Yuga was found out to be (computed to be) of a duration of 4,32,000 years.

Every 4,32,000 years, all the planets except Rahu should congregate at the beginning of Aries, is the revelation found out by the sages.

Twice this duration was Dvapara Yuga having 8,64,000 years.

Three times the Kali Yuga duration is Treta Yuga, i.e. 12,96,000 years.

Four times the Kali Yuga duration is Krita Yuga, for 17,28,000 years.

Having known by now, that the computation started only after 11,700 BP - when Vaivasvata Manu himself was not yet born - we can safely assume that Rama was NOT born in Treta Yuga of this scale but only after 10,700 BP.  Rama, coming in the lineage of Ikshvaku, the son of Vaivasvata Manu, his time period could only be after this cut-off year of the Younger Dryas.

The congregation of all the planets was yet to happen when the calculations were made by the sages sometime after 11,700 BP. In other words, the Vedic society had NOT lived long for thousands of years to physically see the congregation in the previous yuga of Dvapara which started 8,64,000 years before the start of Kali Yuga. It was hypothetical at the time of calculation, but checked regularly with continuous monitoring of the planetary movements.

This can be said for sure considering the difference in the duration of a day of Brahma given by Aryabhata. While all the other ancient texts say that a day of Brahma is equal to 43,20,000  x 1000 years, Aryabhata has differed by saying that it is 43,20,000 x 1008 years. This must have been based on the speed of the planets observed at his time. This also shows that the planetary speed is not constant, but the sages who had watched generationally must have given the average value. Ever since the computation was done (sometime after 10,700 BP), the experts must have been waiting to see the congregation that was due within a few thousand of years. This conjunction was due during the Mahabharata period!

Perhaps for this reason we often find someone or the other in Mahabharata talking about the nature of these Yugas and what to expect in these Yugas. This anxiety factor was missing in Valmiki Ramayana. Only once we see the expression on the reversal of nature in that Yuga, whereas the rest are found in the Uttara Kanda as a regular description of the four yugas. This one instance was that of Malyavan, the maternal grandfather of Ravana telling Ravana that when Dharma swallows Adharma it becomes Krita Yuga. When Adharma swallows Dharma, it brings out Tishya Yuga![9]

dharmo vai grasate 'dharmaṃ tataḥ kṛtam abhūd yugam

   adharmo grasate dharmaṃ tatas tiṣyaḥ pravartat

Tishya was the name of Kali Yuga, originally given by the sages. Tishya is the other name for Pushya that stands for growth, but the description is that of Adharma flourishing! Before going in to the reason for this name, let me point out what Malyavan said further. He continued to say that when Ravana was going around the world, Dharma was destroyed and Adharma was favored by him. He succinctly implied that Kali Yuga was formed by him wherever he went. This was told in Treta Yuga, when Rama was said to have been born.

Treta Yuga occurred sometime after 11,700 BP. And Kali Yuga was created wherever Ravana went.

So what are these Yuga durations?

How was a Yuga determined within these few thousand years?

If Yugas can fuse with one another, what is the relevance for the start of Kali Yuga identified with planetary congregation?
