One could call the Vedic mantras as a “revelation” because the ancient Rishis clearly stated that they are apaurusheya, which means that they are not created by humans. This revelation however is not comparable with the so called revelations of Christianity and Islam, because it is not about a claim which can never be verified and which is not conform to common sense, like the claim, “if you don’t believe that this book contains the full truth you burn in hell forever.”
