The Kurma Purana is one of the eighteen principal Puranas, as stated in the Shrimad-Bhagavatam (SB 12.7.23-24). Srila Bhaktisiddhanta Sarasvati ?hakura remarks that only two kha??as of the Kurma Pura?a are now available, namely the Purva-kha??a and Uttara-kha??a. Sometimes it is said that the Kurma Pura?a contains six thousand verses, but according to Srimad-Bhagavatam the original Kurma Pura?a contains seventeen thousand verses. It is considered the fifteenth of the the eighteen Maha-pura?as.
