Shankara understood Buddhist thought, while the author of the commentary shows misunderstandings of Buddhist thought. The commentary uses the terms vijnapti and vjnaptimatra, which is "a uniquely Buddhist usage", and does not appear in Shankara's commentary on the Brahma-sutras. The two commentaries also quote different Upanishads.
