Tamāla Kṛṣṇa: "He goes on with his self-realization activity undisturbed by material reactions." 70: "A person who is not disturbed by the incessant flow of desires that enter like rivers into the ocean, which is ever being filled but is always still, can alone achieve peace, and not the man who strives to satisfy such desires."
Prabhupāda: Now, here is the... A materialistic person, he has his desires. Suppose he is doing some business, he is getting money. So he fulfills his desire in materialistic way. But a Kṛṣṇa conscious person, suppose he is doing in the same way, he is also planning or doing something after (for?) Kṛṣṇa consciousness. So these two different spheres of activities are not on the same level.
