One who is imperfect, one who is subjected to so many defects of life, we cannot accept knowledge from them. This is our Kṛṣṇa consciousness movement. We don't accept. We accept knowledge from the Vedas, which is perfect. As I have several times explained, that Veda says that stool of animal is impure.
Again, Veda says that the stool of cow is pure. Now, you will say, "Oh, this is contradictory. Sometimes it is said pure, and sometimes . . . this cow is also animal. First of all you said that the stool of any animal is impure, and again you say the cow dung, the stool of another animal, is pure." It is fact—it is pure. So if we accept the standard perfect knowledge from the Vedas, or one who knows the Vedas, then our knowledge is perfect.
Therefore in the Bhagavad-gītā Kṛṣṇa says:
- tad viddhi praṇipātena
- paripraśnena sevayā
- upadekṣyanti te jñānaṁ
- jñāninas tattva-darśinaḥ
- (BG 4.34)
One who has seen the Absolute Truth, or one who has known the Absolute Truth, go there and take knowledge by surrendering. Praṇipātena. Praṇipāta means surrendering. Paripraśnena. Don't make question, waste his time. After you surrender, after you render service, then make question. Otherwise, there is no need of question. Don't waste your time, don't waste his time.
