There is little information on Sivadasa Sen. From what is available, it is known that he was born (somewhere between 1454 - 1474 AD) in the Vaidya guild to Ananta Sen in Malancika, a village in Bengal. Another indication of his birthplace is from his name viz., Sen and that he was a Vaisnava.
Sivadasa Sen's commentary on Caraka Samhita is known as Tattwa-candrika and was written in 1448 CE--however, only Sutra-s 1-27, are still available today. The manuscript belongs to the Bombay Royal Asiatic Society Library.
