The Advaita Vedanta philosopher Gaudapada has used words like “Buddha,” “Asparsayoga,” and “Agrayana” in a few verses in his Māṇdūkya Kārikā which is a metrical commentary on the Māṇdūkya Upaniṣad—this has led many scholars to suggest that Gaudapada was either influenced by Mahayana Buddhism or was a Buddhist philosopher. But this is denied by the scholars of the Advaita Vedanta school. They note that Gaudapada is not referring to the traditional founder of Buddhism when he uses the word “Buddha”; he is denoting the knower of the truth. On the usage of “Asparsayoga,” they note that this term is not the same as the Buddhist concept of “Nirvana”— “Asparsayoga” in Advaita Vedanta tradition means the state of bliss that is achieved when there is no contact (no sparsa) of the senses with their objects but only with the self or the atman; it certainly cannot mean nirvana, which in the Buddhist tradition means total oblivion—the presence of the term “yoga” in “Asparsayoga” indicates that this concept is not pointing towards oblivion but at the attainment of Ultimate Reality which is the Brahman (the underlying principle of the universe). It’s suggested that the word “Agrayana” (which Gaudapada uses only once in his Kārikā, in the verse 90) denotes Mahayana, a major school of Buddhism, but the Advaita Vedanta school holds that Gaudapada’s usage of the word has nothing to do with Mahayana; he means “Prathamatah”, that is, in the first place. Gaudapada’s dates are mired in controversy—he has been placed between the 5th and 7th centuries AD on the basis of the general consensus that his great follower Shankara was born in 788 AD. But some scholars have used historical references to place Shankara in the second century BC—if this is true, then Gaudapada could be a predecessor to the Mahayana Buddhist thinkers like Nagarjuna. In his work, Shankara has tried to move Advaita Vedanta away from Buddhism by noting the differences between the two schools—for instance, in his commentary on the Katha Upaniṣad, Shankara notes that while Hinduism believes in the existence of the atman (soul), Buddhism denies it.
