This is Part 4 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 on 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.

In this part the problems with the Milankovitch theory of precession are analysed in the light of the recent findings on the science front, particularly the acceleration of the rate of precession noticed at present which cannot be explained by the current model of the luni-solar influnce on precession.
There is another issue of complete absence of axial precesison of the earth, that is fundamental to the current theory
of precession. A detailed blog on this based on the evidence from the ancient
monuments was already posted here
in September 2020
Having established that there is no axial precession
of the earth with reference to the sun the probable cause for the movement of the
equinox that is noticed only with reference to the outer space is probed and proposed to be caused by the shape of the path taken by the sun as
it moves across space.
In this context an anomalous observation on the earth is brought to the fore. This is witnessed at the solstice limits in the two hemispheres of the earth as a shift in the solstices at the rate of 15 meters per year.
Shift of the Tropic of cancer in Mexico
This means the solstice crosses one kilometer in 66.66 years,
which is exactly the average rate proposed by Surya
Siddhanta for the shift in the equinox per degree. In other words, for every degree of movement of the equinox
there is a corresponding shift in the inclination of the earth detected by 1 km
shift in the solstices. This is surprising given the fact that the earth’s
axis doesn’t tilt and that earth maintains the same angle of tilt with the sun.
Then what causes this shift?
No scientist had taken this shift seriously under
the assumption that this shift is caused by the changing axial tilt of the
earth. But now having known that such a
tilt is not at all happening, the question remains what causes the sun’s solstice limit to move
northward?
Is the entire plane of the solar system getting
tilted as the sun surges ahead, by which the sun is seen to glide up with reference to the earth?
An unknown feature of the sun’s movement and also
the tilt of the plane of the solar system are waiting to be discovered.
The current movement would reverse in
future is what we gather from the inputs on solstice limits given in the Indic
texts. The tropic of cancer crosses the center of India. Presently it passes through Karkoteswar
temple in Ujjain. A compilation of all the inputs on the location of the tropic
of cancer in the past given as Jambu Marga in Mahabharata shows there is a minimum of three solstitial
bands (current, further north in Rama’s
time and further south in Skanda’s
time) justifying the Yuga of Ayana of Munjala!
There are 2 Yugas of Ayana moving within the Jambu
Marga comprising of 6 rounds of 7200 years each. Glaciation and de-glaciation had alternated due to
the change in the inclination of the sun or the solar system or the yet to be
discovered X factor leaving an imprint by means of the solstice shadow on the earth that our ancestors had so
meticulously watched over many rounds of cycles of the equinox. For
details, request the interested readers to procure a copy from the
website cited earlier.
The cross-check of the paleoclimatic data is done
with these Indic cycles in the next (the last) part of the series to show that
the Indic cycle is true to the core and is waiting to be discovered sooner than
later by the scientists.
