One must give up for good all the propensities for sinful activities. Then take to Kṛṣṇa consciousness and it will act. Otherwise, if you go on keeping both the lines that, "Whole day I shall commit all sinful activities, and at night I shall chant . . ." Just like in Christian Church there is a system, confession: at the end of the week they go to the church and they confess before the priest, "I have done so many sinful activities." So pray something and he says: "All right, excused." Again, from Monday, begins sinful activities. Yes. Not like that.
Once you stop sinful activities, you cannot commit again. Then Kṛṣṇa will save you. Ahaṁ tvāṁ sarva-pāpebhyo mokṣayiṣyāmi (BG 18.66). Kṛṣṇa is not so fool that you simply once surrender to Him and then commit sinful activities and again surrender to Him. No. That will not be allowed. Kṛṣṇa can excuse you once or twice, but if you commit . . . (break) . . . offense, then it will act and people will be benefited. Chindanti kovidās tasya ko na kuryāt kathā-ratim.
So kathā-rati, attraction for kṛṣṇa-kathā. Simply let us hear, let us chant, let us think of Kṛṣṇa. That will make us very much rapidly progressive on the spiritual path.
