Prof. Regamay: Everything is done by Kṛṣṇa, and we are only the tools for Him.
Prabhupāda: Everything is done by Kṛṣṇa, that's all right. But ye yathā māṁ prapadyante (BG 4.11). As you want Kṛṣṇa to do, He says: "Only just surrender unto Me." He wants that. But you want so many things. Therefore He gives facility, "All right, do it, at your risk." He doesn't want. He says: "Give up all this nonsense." Sarva-dharmān parityajya mām ekaṁ śaraṇam (BG 18.66). "Just surrender unto Me." That He wants. But because we will not do that, we want to do something else, but I cannot do without His sanction, therefore He sanctions. That means Kṛṣṇa does everything. But I want to do, and simply I want His sanction. Therefore, out of His causeless mercy, He agrees, "All right, do it." But you'll have to get the result of it.
