述曰。彌沙塞云。欝摩王第四子尼樓。本行經尼俱。此翻為別成。祐律師。指懿摩王。是釋種之先。第四子莊嚴。是白淨所承。南山。指懿摩。即第十輪王。去菩薩一百世。第四子莊嚴。即白淨所承。其說略同（別承莊嚴。兩譯不同。秖是尼俱一人）。

The author remarks: The Mahīśāsakas state that the fourth son of King Ikṣvāku was Nilou; the *Benxing jing* gives Niju, translated here as 'Biecheng' (Separately Accomplished). Vinaya Master You points to King Ikṣvāku as the ancestor of the Śākyas, and the fourth son Zhuangyan as the one from whom Śuddhodana descended. Nanshan points out that Ikṣvāku was the tenth wheel-turning king, a hundred generations removed from the Bodhisattva, and that the fourth son Zhuangyan was the one from whom Śuddhodana descended. Their accounts are broadly similar. ('Biecheng' and 'Zhuangyan' are different translations; they are merely the single person Niku.)
