CC Madhya 9.200
tāra madhye āilā pativratā-upākhyāna
There, among the brāhmaṇas, Śrī Caitanya Mahāprabhu listened to the Kūrma Purāṇa, wherein is mentioned the chaste woman’s narration.
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.
