Now, here somebody may say that "This is too much sectarian, that knowing simply Kṛṣṇa, everything is known." Somebody may say like that. But actually this is the fact. The Vedic statement says like that.
Devotee: "Full in scientific knowledge is Kṛṣṇa, and everything is revealed to the person in Kṛṣṇa consciousness. In complete Kṛṣṇa consciousness, one knows that Kṛṣṇa is the ultimate knowledge, beyond any doubts."
Prabhupāda: Now, here somebody may say that "This is too much sectarian, that knowing simply Kṛṣṇa, everything is known." Somebody may say like that. But actually this is the fact. The Vedic statement says like that. Kasmin tu bhagavo vijñāte sarvam idaṁ vijñātaṁ bhavati. If you can understand the origin, person, the original person... The Upaniṣad does not say directly, "The original person is Kṛṣṇa," simply because there are so many impersonalists. But the Upaniṣad gives hint that if you can understand the original person, kasmin... This is person. Kasmin vijñāte: "If one is able to understand the Supreme Person," sarvam idaṁ vijñātaṁ bhavati, "then everything becomes known." How? Suppose you want to know... Say I am a foreigner. If I want to know how this American government is going on, oh, I will have to study so many things. But somehow or other, if I made friendship with Mr. Nixon, the president, and if I sit down with him a few days, oh, everything is known. Is it not? Yes. He will disclose everything, that "My government is going on like this." You know. So this is a fact. If you try to understand or if you some way or other understand the original person, Kṛṣṇa, then you understand everything. That will be explained here. Simply by knowing Kṛṣṇa you will understand everything. This wonderful thing is in Kṛṣṇa consciousness. Simply try to understand what is Kṛṣṇa and you will gradually understand everything. This is the secret of Kṛṣṇa consciousness. And that's a fact.
