 To show that the Veda was the only correct scripture, Kumārila ingeniously said that ""the absence of an author would safeguard the Veda against all reproach"" (apaurusheya).There was ""no way to prove any of the contents of Buddhist scriptures directly as wrong in spirit..."", unless one challenges the legitimacy and eternal nature of the scripture itself.It is well known that the Pali Canon was composed after the Buddha's parinirvana.
