Prabhupāda: Still, vijñāna means jñāna and viveka. Viveka means personal conviction. That is called vijñāna. Jñāna and vijñāna. One knowledge you get from me, and then you practically apply your consciousness that "Yes, what Prabhupāda has said, it is right." That is called vijñāna.

Prabhupāda: So how Kṛṣṇa has prepared earth? That I want.

Prabhupāda: No, they do not know, but we know. How in your abdo . . . belly gas is formed? How? There was no gas, but automatically the gas is formed. And therefore sometimes, if it is much gas, then you go for treatment. So this is the practical. The gas is also generating from my body. So as I am an individual, insignificant body, if there is possibility of generating little gas, so Kṛṣṇa's gigantic body, why not gigantic volume of gas? This is the explanation.
