v2.c35.s1.3

He writes that the episode of Purāṇa of Dakkhiṇāgiri² in the account of the first council marks the difference between the Theravādins and the Mahīśāsakas. In course of time, that group of monks who held Purāṇa in high esteem formed the Mahīśāsaka school by including his seven rules not accepted by Mahākassapa in his Vinaya code. In the Mahīśāsaka Vinaya, the second place of seniority is awarded to Purāṇa, the first being given to Kauṇḍinya. The Mahīśāsakas assert that after the deliberations of the first council were finished, the texts were once more recited for the approval of Purāṇa, who accepted the same after adding his seven rules.
