Morning Walk -- February 6, 1976, Mayapura: Dayānanda: So how is it possible that... We're so insignificant, but at the same time we become so puffed up? How is it possible for us...? Prabhupāda: That is material consciousness, that you are nothing you are thinking very big. That is material consciousness. And as soon as you become Kṛṣṇa conscious, you'll simply think, "Kṛṣṇa is great; we are nothing, insignificant." That is Kṛṣṇa consciousness. And so long you think that you are independent of Kṛṣṇa—you are also another Kṛṣṇa—then you are fool, rascal. Mūḍho 'yaṁ nābhijānāti loko mām ajam avyayam ( BG 7.25). Hṛdayānanda: That's our madness. Prabhupāda: Madness. The whole world is going on on this foolish understanding. Therefore they have been described, mūḍha, all rascals. Anyone who is thinking, "There is no God, there is no Kṛṣṇa, it may be He is impersonal, there is no personality, and I am equal to Him"—these are all rascals, fools. Dayānanda: So actually there is no way to become detached. Prabhupāda: The only way is that you become Kṛṣṇa conscious. Dayānanda: Except through Kṛṣṇa. Prabhupāda: Yes. Mām eva ye prapadyante. You surrender to Kṛṣṇa and everything will be clear, just like as soon as the sun rises, everything is clear, no covering. That is our propaganda, that you become Kṛṣṇa conscious; then you become fully aware of everything. Otherwise you remain rascal, fools, gādhā, asses. If you prefer to remain asses, you can do so, but we are servant of Kṛṣṇa. We must preach real, reality
