“I go on committing all kinds of sinful activities, and sometimes I go in the temple and chant Hare Krsna and dance,” no, don’t take this policy. You must stop your sinful activities. Hare Krsna mantra has got the power to neutralize the resultant action of your all sinful activities. That’s a fact. But don’t accumulate again the sinful activities. Then you are safe. If you take it as an instrument: “Now let me commit sinful activities and chant Hare Krsna,” then that is very dangerous.
