3:11 1. There is plenty of historical research showing classical astrologers using sidereal zodiac signs. [So how can you say they weren’t?]
5:48 2. Statements in Hora Ratnam and Vasishtha Samhita show that the sidereal zodiac has been dominant in India since olden times. [So how can you say it wasn’t?]
8:05 3. Why would India adopt the sidereal convention, when the rest of the world did just the opposite?
8:52 4. Doesn’t Sūrya Siddhānta establish a sidereal zodiac in the First Chapter?
11:47 5. Doesn’t Sūrya Siddhānta’s Third Chapter reveal that it is meant for producing sidereal charts?
13:39 6. Don’t the Purāṇas and Siddhāntas establish a sidereal zodiac when they describe the relation between Aries and Aśvinī?
18:25 7. Does Viṣṇu Purāṇa establish the co-existence of Tropical and Sidereal zodiacs by its reference to bhu-bhuva-sva?
19:20 8. Why does anyone try to say one system is right and the other is wrong? They are just used for different things! Tropical is a seasonal zodiac, used for calendars and weather. Sidereal is a stellar zodiac used for natal astrology.
23:31 9. If it is true that the zodiac should be tropical and the nakshatras should be sidereal, why are you the only one who realizes it?
25:15 10. If you are right, are all the sidereal astrologers wrong?
25:53 11. What actually changes in the charts, if we use your system?
26:22 12. Are the Jyotisha classics like Parashara Hora, Brighu Samhita, etc meant to be used with tropical signs?
26:49 13. Don’t the classic texts simply say what zodiac we should use?
27:15 14. How can Asvini not be at the beginning of Aries!? How can Maghā not be in Leo?
28:19 15. How would you explain the 12 symbols of the Zodiac which most people say were originally taken from Egyptian sidereal constellations?
29:40 16. Why don’t you do chart reading comparisons, to demonstrate that tropical zodiac is more accurate than the sidereal zodiac?
30:49 17. If the Zodiac signs are tropical how are astrological ages determined?
31:12 18. What IS “Vedic” astrology, if it’s not sidereal?
32:31 19. What does this debate reveal about ourselves as astrologers and human beings? How can that revelation improve the astrological community?
33:15 20. I’ve heard that tropical and sidereal astrology was aligned in the same signs/ degrees 2,000 years ago. What is your viewpoint on this?
34:10 21. What is the difference between the way you and Ernst Wilhelm way of calculate nakshatras?
34:46 22. Are there 27 or 28 nakshatras?
35:55 23. If the nakshatras are constellations, why are they all of equal size, 13 degrees 20 minutes?
36:42 24. Why did ancient Vedic Astrologers consider Krṛtikā the first nakshatra?
For exact references where the tropical zodiac is defined in the Purāṇas and Siddhantas, please see vicdicara.com/tropical Viṣṇu Purāṇa does the same in book 2, chapter 8.
Mul.Apin reference of the equinox to Libra: 1.3.1-12. See vicdicara.com/tropical for the full quote.
Regarding ancient sidereal skies that were NOT the 12-sign zodiac: To name a few, Babylon’s Mul.Apin specifies 18 constellation divisions. Egyptians had 33. Asia, including India, had 27 or 28.
For Varaha Mihiria’s 6th century statements of trepidation about people not caring where the solstices actually where, see Pancha Siddhantika 3.31-32 & Bṛhat Samhita 3.1-3
For an explanation of how the solstices and equinoxes make sense of the elements and modalities of signs, and for more elaboration on the logic of the tropical zodiac, please see my segment in this debate video: https://youtu.be/C2-TueFPoFE
Re: Lahiri commission on tropical – “This recommendation is to be regarded only as a measure of compromise, so that we avoid a violent break with the established custom. But it does not make our present seasons in the various months as they were in the days of Varahamihira or Kalidasa. It is hoped that at not a distant date, further reforms for locating the lunar and solar festivals in the seasons in which they were originally observed will be adopted.” (Calendar Reform Committee Report, p. 5)
