Prabhupāda: No, they cannot be because they did not find out what is the ultimate source. They could not. Therefore they cannot be satisfied. If . . . A really scientist, how he can be satisfied? The goal is not yet achieved. How they can be satisfied? But we are satisfied because we know that the goal, the cause, ultimate cause, is Kṛṣṇa. (break) . . .instruction is not blind. It is fact. Just like my body is there, and on account of my energy, so I am getting flesh, I am getting nail.
Acyutānanda: Yes. They cannot explain how the body transforms into . . .
Prabhupāda: Yes.
Acyutānanda: . . .tissue.
Prabhupāda: Yes. But explain or not explain, I am seeing practically that two things are coming out: one, the skin, where there is sensation; and where, this nail, there is no sensation. This is matter and spirit. Where there is consciousness, that is spirit. Where there is no consciousness, that is matter.
Hṛdayānanda: Very good example.
Prabhupāda: Hmm?
Hṛdayānanda: Very nice example.
Prabhupāda: But both of them are coming from me. So this sensation, this consciousness, is perfect when it comes to Kṛṣṇa consciousness. This is developing; in every living entity is developing. The consciousness, the sensation, is there in the tree also, but he is not developed. When the same consciousness comes to the complete perfection, then he understands, "Oh, here is Kṛṣṇa." Bahūnāṁ janmanām ante jñānavān māṁ prapadyate (BG 7.19). That is perfection. Vāsudevaḥ sarvam iti: "The real source is Vāsudeva." Oṁ namo bhagavate vāsudevāya. Then he glorifies Vāsudeva. But to know Vāsudeva, you make research. That is one way, going on. But if you accept . . . Vāsudeva says, "I am everything." Then accept immediately. The whole solution is there. Two, two ways: āroha-panthā, avaroha-panthā. You are trying to search out. Go on.
