Lord Buddha decried the authority of the Vedas

Expressions researched:
"decried the authority"

SB Canto 1

The Lord incarnated Himself as Buddha and decried the authority of the Vedas in order to stop animal sacrifice in the name of religion. This was foreseen by Nārada, and therefore he condemned such literatures.

SB 1.5.15, Purport:

Śrīla Vyāsadeva is the authority in Vedic explanations in the Mahābhārata, etc., and his encouragement in sense enjoyment in some form or other is a great barrier for spiritual advancement because the people in general will not agree to renounce material activities which hold them in material bondage. At a certain stage of human civilization when such material activities in the name of religion (as sacrificing animals in the name of yajña) were too much rampant, the Lord incarnated Himself as Buddha and decried the authority of the Vedas in order to stop animal sacrifice in the name of religion. This was foreseen by Nārada, and therefore he condemned such literatures. The flesh-eaters still continue to perform animal sacrifice before some demigod or goddess in the name of religion because in some of the Vedic literatures such regulated sacrifices are recommended. They are so recommended to discourage flesh-eating, but gradually the purpose of such religious activities is forgotten, and the slaughterhouse becomes prominent. This is because foolish materialistic men do not care to listen to others who are actually in a position to explain the Vedic rites.

Srimad-Bhagavatam Lectures

So the Vaiṣṇava can understand what is Lord Buddha and why he decried the authority of... Because there was no other way.

Lecture on SB 7.6.1 -- Madras, January 2, 1976:

The Buddhists, they decry the authority of Vedas. He had to do that. There was no way. Jayadeva Gosvāmī offered his prayer to Lord Buddha. Nindasi yajña-vidher ahaha śruti-jātam. Śruti. In the Vedas there is recommendation of yajña, and in some of the yajñas there is recommendation of killing paśu. So Lord Buddha, he preached ahiṁsā paramo dharma, no killing of animals. So these paṇḍitas, they will give evidence that in the Vedas there is description of killing animals. How you can stop it? So therefore he said, "I don't care for your Vedas." Nindasi yajña-vidher ahaha śruti-jātam. Why? Why he did so? Sadaya-hṛdaya-darśita-paśu-ghātam. He was so much compassionate to see unnecessary killing of animals. Sadaya-hṛdaya. Therefore ahiṁsā paramo dharmaḥ. That was his... Although he is the incarnation of God... Keśava dhṛta-buddha-śarīra, jaya jagadīśa hare. So the Vaiṣṇava can understand what is Lord Buddha and why he decried the authority of... Because there was no other way. So

nindasi yajña-vidher ahaha śruti-jātaṁ

sadaya-hṛdaya darśita-paśu-ghātam

keśava dhṛta-buddha-śarīra jaya jagadīśa hare

So a Vaiṣṇava can understand what kind of part he is playing. So in this way there are different activities going on, and they have been taken as different types of dharma. But real dharma is bhāgavata-dharma. Therefore Kṛṣṇa says, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). This is dharma. That is called bhāgavata-dharma, intimate relationship with the Lord, Bhagavān. Brahmeti bhagavān iti... Brahmeti paramātmā iti bhagavān iti. Tattva-vit. Vadanti tat tattva-vidas tattvaṁ yaj jñānam advayam (SB 1.2.11).

1974 Conversations and Morning Walks

Now, my point is that Buddhism was rejected from India because he's decried the authority of Vedas

Morning Walk -- March 29, 1974, Bombay:

Prabhupāda: You cannot deny the authority of Vedas. Suppose you are following ahiṁsā, you cannot say that "State should not anymore hang anybody." That you cannot say. You follow.

Indian man (3): Shall I read it?

Prabhupāda: Yes.

Indian man (3): Vabhicaro na kartavyaḥ pumvi stri...(?)

Prabhupāda: Now, my point is that Buddhism was rejected from India because he's decried the authority of Vedas.

Indian man (3): So this fellow also will be rejected.

Prabhupāda: That... Yes, immediately. Because he does not accept the authority of Vedas. That is real knowledge. Nindasi yajña-vidher ahaha śruti-jātam Yes, yajña, I mean to say, criticize the yajña-vidhi. Yajña-vidhi you cannot criticize. Yajñārthāt karmaṇo 'nyatra loko 'yaṁ karma-bandhanaḥ (BG 3.9). Karma-bandhana. So yajña must go on, and the vidhi must be followed. That is real acceptance of Vedic knowledge. If you manufacture your own concoction, "This is good, this is bad," that will not help you.

Indian man (3): Vetas pi pavitranam svadhinam ca tasam api, vedanam ca na kartavyam nindha saddhya...(?)

Prabhupāda: But why he's making nindā? You don't eat, even it is... Now in the first you said, you don't..., you cannot kill animal, even if it is...
