 Modern scholars such as Allan Dahlaquist disagree, however, and state that the borrowing may have been in the other direction, from Dharmasutras into the Purana.Other chapters, particularly those in book 5 and 6 of the "Vishnu Purana" have Advaita Vedanta and Yoga influences.The theistic Vedanta scholar Ramanuja, according to Sucharita Adluri, incorporated ideas from the "Vishnu Purana" to identify the Brahman concept in the Upanishads with Vishnu, thus providing a Vedic foundation to the Srivaishnava tradition.
