This is Part 5, the last part of my paper on the Siddhantic concept of the equinoxes offering newer insights into emerging trends in Science on Precession.

Part 1 of my paper (August 2020 ) gives an outline of the western and the Indic model of precession of the equinoxes and a comparison between the two. The Indic model does not support continuous precession but an oscillatory to and fro movement of the equinoxes of a circle of 108˚ covered in 7200 years at an average rate of 54 arc seconds per year or 1 degree in an average of 66.66 years.

Part 2 of my paper (September 2020 ) addresses the objections to the Indic model in the light of “a very difficult passage” in Siddhanta Shiromani on a different version from Surya Siddhanta and Munjala and resolves them by drawing up the three types of cycles as shown below.

Part 3 of my paper (November 2020) brings to the fore the textual, epigraphic and iconographic evidence on the limited to and fro motion of the equinoxes, besides the sidereal representation of the equinoxes and the corresponding polar shift within the constellation called Shishumara (Ursa Minor) as outlined by the various Indic texts.

Part 4 of my paper ( February 2021) discusses the problems in the Milankovitch Theory, outlines the Indic model of three cycles and the Band of Tropic of Cancer known as Jambu Marga within which the solstitial limits move up and down in three cycles in tune with the to and fro motion of the equinoxes. Three cycles make up one Yuga of Ayana, mentioned by Munjala. Two Yugas of Ayana are equal to the span of 41,000 years that match with climatic changes.

This last part outlines the historical beginnings from Skanda’s time that match with the change of an Epoch when de-glaciation started in the Southern hemisphere causing a series of Meltwater Pulses.

The oral tradition of Narrangga people of Yorke Peninsula in Southern Australia of a sea breach around 12,000 years ago match with the sea flood at Skanda’s time around the same time. The to and fro ayana cycles are mapped to check the de-glaciation at Skanda’s time and in the periods before him and after him.

It is found that the glacial events since the Last Glacial Maxima (33k years ago) had alternated with a gap of approximately 6500 years. This is not supported by the Milankovitch cycles but is found close to the Indic Ayana cycle of 7200 years. With more evidence coming in support of much shorter cycles of 1000 and 2000 years known as Dansgaard-Oeschger (DO) events, they were super-imposed on the Indic to and fro cycles to check for concurrence.

The DO events are found to have occurred within 1200 years on either side of the midpoint of the Indic Ayana cycle at zero degree Aries. In other words, increased insolation followed by de-glaciation was on the higher side in the mid region. The absence of the DO events in the edges match with colder times and mini Ice ages as was witnessed in the 17^th century.

Based on the variations in the rate of trepidation of the equinoxes and Dansgaard –Oeschger events matching with the Ayana cycles, it is proposed that the sun is taking a helical or sinusoidal path. While we await corroborative discoveries in this regard, what cannot be easily displaced is the time tested Indic wisdom of to and fro movement of the equinoxes.

Path of the Sun, detected in the movement of the equinox

The precession record (Table 1 in Part 1 of the series) showing faster movement around the mid-point, with steady slowing down until now and a gradual acceleration in speed noticed in the past century has no explanation in any scientific theory but only in the Siddhantic version of the movement of the equinoxes, as the sun surges in a helical path. 

Hypothetical path of the Sun

* Today we are close to one edge of the curved path of the sun by having come closer to the 27 degree distance from the zero point of Aries. Severe winters have been witnessed since the 17th century. 

* The earth's rotational speed has increased by 3 minutes compared to the 19th century data with the Pancanka writers. 

* The earth was found to have rotated faster than average on a record number of 28 days in the year 2020, ever since the monitoring started fifty years ago. 

* There is a spurt in the rate of precession in the past one century. 

With these early indicators for a reversal in the direction of the equinoxes, the day is not far off to see the Siddhantic model of to and fro motion getting the attention of the scientific community. 

My effort is a squirrel's part to pick out a few grains known to me in laying the foundation for a revival of this unrecognized science perfected by our ancient sages.
