I want to know the answer to the following question:
The original Veda of the rishis was altered by a few Brahmins who introduced what?
All the background I'm provided with is that "However, the Buddha was not anti-Vedic, and declared that the Veda in its true form was declared by "Kashyapa" to certain rishis, who by severe penances had acquired the power to see by divine eyes.". Is that enough to answer the question?
