Devotee: We have been here for many lifetimes performing sinful activities. So is it possible to counteract all those sinful activities in one lifetime, or does it require many...?
Prabhupāda: One minute. That is Kṛṣṇa consciousness movement. One minute. You are not reading Bhagavad-gītā? What Kṛṣṇa says? Sarva-dharmān parityajya mām ekam śaraṇaṁ vraja, ahaṁ tvāṁ sarva-pāpebhyo mokṣayiṣyāmi: [Bg. 18.66] "You surrender unto Me. Give up your all business. I will give you relief from all sinful reaction immediately." So it requires one minute. "My dear Kṛṣṇa, I was forgotten. Now I understand. I fully surrender unto you." Then you become immediately free from all sinful reactions. Without any reservation, without any politics, if you fully surrender, Kṛṣṇa is assuring, ahaṁ tvāṁ sarva-pāpebhyo mokṣayiṣyāmi mā śucaḥ. He reassures, "Don't worry whether I will be able to give you relief from all reaction." Mā śucaḥ. "Finished, guaranteed. You do this." So how much time it requires to surrender to Kṛṣṇa? Immediately you can do that. Surrender means you surrender and work as Kṛṣṇa says. That is surrender. What Kṛṣṇa says to do? Man-manā bhava mad-bhakto mad-yājī māṁ namaskuru [Bg. 18.65]. Four things: "You always think of Me, and you become My devotee, you worship Me, and offer your respect, full obeisances unto Me." You do these four things? That is full surrender. Mām evaiṣyasi asaṁśaya: "Then you come to Me without any doubt." Everything is there. Kṛṣṇa has given everything fully. If you accept it, then life is very simple. There is no difficulty.
