So the point is that although in the Vedic scripture there is recommendation that animal sacrifice allowed, but that is not meant for killing. That is giving a new life. So when this animal sacrifice was going on simply for eating, simply for eating... Just like in a particular mission they say that "We are devotees of goddess Kālī." Their real mission is to eat meat. Therefore they have become devotees of goddess Kālī. But actually, these sacrifices were not meant, as explained by Caitanya Mahāprabhu, for killing the animals. That was to test the power, the strength, of the Vedic mantras. So Lord Buddha's movement was therefore started... When people began to eat meat like anything on the plea of Vedic sacrifice, so Lord Buddha, at that time—Lord Buddha means he's also incarnation of Kṛṣṇa—he appeared to stop this animal killing. That is the prayer of Lord Buddha we sing:
- nindasi yajña-vidher ahaha śruti-jātaṁ
- sadaya-hṛdaya darśita-paśu-ghātam
- keśava dhṛta-buddha-śarīra jaya jagadīśa hare
The buddha-śarīra... Just like we offer prayer to Nṛsiṁha-deva,
- tava kara-kamala-vare nakham adbhuta-śṛṅgaṁ
- dalita-hiraṇyakaśipu-tanu-bhṛṅgam
- keśava dhṛta-narahari-rūpa jaya jagadīśa hare
Similarly, there is prayer for Lord Buddha also. The, that prayer is: nindasi yajña-vidher ahaha śruti-jātam, "Although in the Vedic literature there is recommendation for animal sacrifice, you are forbidding, 'No, this should not be done.' " Therefore Buddhism is not Vedic religion, because he was against this Vedic sacrifice. Sadaya-hṛdaya darśi... His main business was to stop this animal killing, but people wanted to give evidence from the Vedas. Therefore he said, "I don't care for your Vedas." Veda nā māniyā bauddha haila nāstika. Therefore Śaṅkarācārya came, and he drove away the Buddhists from the land of India. That's a long history.
