Watch the spiral path taken by the sun moving around the galactic center. But this is the easy part. Visualize the geocentric view of the apparent motion of the sun.

According to @jayasartn, the oscillatory model of the precession in Surya Siddhanta (ie tropical vernal equinox oscillating around side-real vernal equinox with an amplitude of 27° amplitude) is based on this spiral motion of the sun.

"The Sun orbits the center of our galaxy tipped at an angle of 60 degrees. Over the course of its orbit, our star also bobs up and down above and below the galactic plane."

This article on the accuracy of the video in the first tweet of this series. It's pretty accurate.

Just as an imaginary language Proto Indo-European was created by Western Padre Linguists to explain the presence of Sanskrit words in European languages, the same way this "GapodBazi" of Indians borrowing astronomy knowledge from Greeks and Babylonians has been perpetuated.

Prof KS Shukla summarizes it as follows:
"Aryabhata-I hypothesized that planets move in eccentric circles and epicycles.

The eccentric and the epicyclic theories of Aryabhata I have been explained in greater detail by Bhaskara I in his Maha-Bhaskariya (ch. iv)........

See this. The tragic story of Padre Indology of White man taking Hindu texts and interpreting them in the light of his own ideas declaring ancient Hindus a fool and copy cat (everything came from outside) continues.

The saddest part is Hindus with the "scientific attitude and logical acumen" (attained with grace from Gora master) keep doing the same to unwashed Hindus after the Gora master is long gone.

The interesting point about the use of ecliptic coordinates coordinate system by Indians in ancient times (as claimed in the paper) instead of polar coordinates (as told by Gora master) is the following:

Surya Siddhanta describes its model for precession of equinoxes as follows:

"त्रिंशत्कृत्यो युगे भानां चक्रं प्राक् परिलम्बते।
तद्गुणाभूदिनैर्भक्ताद् द्युगणाद्यदवाप्यते॥
तद्दोस्त्रिघ्ना दशाप्तांशा विज्ञेया अयनाभिधाः।
तत्संस्कृताद्ग्रहात् क्रान्तिच्छायाचरदलादिकम् ॥"

Hamare Saadhu-Mahatma kahate hain agar need na aaye to Vedanta ka koi text padho aur turant need aa jaayegi. 🤣
So here is something very interesting I came across during last night's bedtime reading. It's about Darwinian evolution and the Upanishads (Vedanta).

"Darwin’s theory of evolution is related to Biological evolution from viruses to unicellular to complex life forms ending up with human beings or Homo sapiens.
2/
According to Prof. Julian Huxley, evolution has peaked with the specialization of conceptual thought processes for humans.

Someone asked me why only three Vedas mentioned by Manu here? Why not four? Probably hinting at Padre Indologist claim that original Vedas were only three and not four.
Here is the explanation. It's in Hindi though.

"वेद चार प्रकार का है- ऋग्वेद, यजुर्वेद, सामवेद और अथर्ववेद । पहले तीन वेदों का नाम ऋक् आदि तीन प्रकार की रचना के अनुरोध से हुआ और चौथे अथर्व-वेद का नाम अध्ययन के कारण से हुआ।
आशय यह है कि जहांपर छन्दके वश पाद(भाग या हिस्सा) की व्यवस्था की जाय वह ऋक्; जहां गान के अनुकूल व्यवस्था हो वह साम; और जहां छन्द तथा गानसे अतिरिक्त गद्यभाग हो वह यजु कहलाता है । यहः ऋक्, साम तथा, यजु का लक्षण जैमिनि-मुनि ने कहाहै- :

"एकादशी सर्वमान्य व्रत है पर इसका अत्याचार दो देशों में अधिक देखा जाता है । एक वङ्ग (बंगाल) में, जहां अदीक्षित बालविधवा भी एकादशी के घोर नियमों से मृतप्राय करडाली जाती हैं। धन्य हैं वङ्गपण्डित महाशय।

"....मनुस्मृति में वही लोग क्षेपक कह सकते हैं जो वैदिकरहस्य नहीं जानते हैं, अथवा जो कोई शब्दत: किंवा अर्थतः वेद के कण्टक हैं। यहां एक सुप्रसिद्ध उदाहरण दिखलाया जाता है-
