The Kurma Purana is one of the eighteen principal Puranas, as stated in the Shrimad-Bhagavatam (SB 12.7.23-24). Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura remarks that only two khaṇḍas of the Kūrma Purāṇa are now available, namely the Pūrva-khaṇḍa and Uttara-khaṇḍa. Sometimes it is said that the Kūrma Purāṇa contains six thousand verses, but according to Śrīmad-Bhāgavatam the original Kūrma Purāṇa contains seventeen thousand verses. It is considered the fifteenth of the the eighteen Mahā-purāṇas.
