But as it contains a large number of illustrative myths and legends, it is of great value as an early collection of stories. It is to a considerable extent based on Yāska's Nirukta. Besides Yāska himself and other teachers named by that scholar, it also mentions Bhāguri and Āçvalāyana as well as the Nidāna Sūtra. A peculiarity of this work is that it refers to a number of supplementary hymns (khilas) which do not form part of the canonical text of the Rigveda.
