The research behind every line

78,375 words of source-cited research, read from the scanned texts on the Internet Archive: the Jyotisha classics, the mathematics from Aryabhata to Ramanujan, Chanakya, the rishis, saints and Siddhars — and an honest look at the market, the law and the evidence. Every claim carries its edition, page or verse, and its copyright status.
