Extracts from book: Brhat Naksatra by Sanjay Rath
[continued]…We are not empowered with this knowledge to debunk theories about avatara is they do not confirm to the requirements of the charts.
Shri Chaitanya is Krishna avatara [True]
Shri Chaitanya: Amsha avatara
Shri Chaitanya appeared on February 27, 1486 at 5:56:40 pm LMT at Navadwip, India (88 E 22?, 23 N 25?) which was a Wednesday on Purnima (S15) tithi in Purva Phalguni nakshatra belonging to Atri-Moon group showing the creation ray. Now, Shri Krishna also comes from the Atri-Moon group with Rohini as the Janma nakshatra.
The second requirement of the Moon and Lagna is also met as the Moon is in Leo Lagna and both are in Purva Phalguni nakshatra having the Atri-Moon ray and showing the possibility of an avatara of Vishnu.
Both Shri Krishna and Shri Chaitanya have Saturn in Jyeshtha nakshatra. The 7th house shows the conditions for reincarnation and in the chart of SHri Krishna, Saturn is in the 7th house in Jyeshtha nakshatra in Scorpio which indicates an island (Mars rules Scorpio) as the likely place and the name of the place of birth of SHri Chaitanya is Navadwip where Nava means ‘new’ and dwip is from dvipa meaning island. The atmakaraka in the chart of Shri Krishna and Shri Chaitanya are the same as the ishta devata indicating the merger of the atman and ishta devata indicator planets implying that the ‘higher and lower bird on a branch’ theory will not apply as the soul is already one who has realised his higher self.
From the above we can safely conclude, based on these criteria that SHri Chaitanya is an amsha avatara (partial incarnation) of Shri Krishna (specific avatara pointer for amsha).
