So Caitanya Mahāprabhu says that veda nā māniyā bauddha haila nāstika. Buddha philosophy, they do not accept the authority of Vedas, although Lord Buddha is accepted as incarnation of Kṛṣṇa. Keśava dhṛta-buddha-śarīra jaya jagadīśa hare. But for the time being, he did not accept the authority of Veda. Nindasi yajña-vidher ahaha śruti-jātam. Lord Buddha was preaching ahiṁsā, so according to Vedic rituals there is prescription sometimes—not always—killing of animals. So when Lord Buddha was preaching ahiṁsā, "No more animal killing," the so-called Vedāntists and Vedic followers, they said, "Why you are preaching in that way? We have got in the Vedas many animal sacrifice is prescribed there, paśu-bali." So Lord Buddha, what he will reply to these foolish persons what was his mission? He said: "I don't care for your Vedas." Therefore nindasi. Nindasi yajña-vidher ahaha śruti-jātam: "Although it is Vedic injunction, my Lord, you have decried." Means there is no way. Why? Sadaya-hṛdaya-darśita-paśu-ghātam: "You are so kind, you wanted to stop this poor animal killing: 'Never mind. For the time being stop Vedic authority.' "
So these things can be understood by the devotees. Although he decried Vedic authority, still, he is worshiped, keśava dhṛta-buddha-śarīra jaya jagadīśa. This is the understanding of the devotees. They know everything perfectly well, what is what. They know Śaṅkarācārya, what he is. Śaṅkarācārya is the incarnation of Lord Śaṅkara, Lord Śiva. Lord Śiva. Vaiṣṇavānāṁ yathā śambhuḥ. He is the topmost Vaiṣṇava. So the devotees know that Śaṅkarācārya was at heart a Vaiṣṇava, but he had to preach like a vaiṣṇava because he had to drive away Buddhism from India. That was the mission.
