So we should not think that because we are chanting we can act all kinds of sinful activities. No. The chanting of Hare Krsna will give you protection, but you should not take advantage of. But if by accident or by unintentionally if you commit some, by habit, that is also excused. That is also stated in the Bhagavad-gita. Api cet su-duracaro bhajate mam ananya-bhak, sadhur eva sa mantavyah [Bg. 9.30]. That is accidental. Not that willful sinful activities should be done and it should be neutralized by chanting Hare Krsna mantra. No. Then you are spoiling your time. That should not be done. So yesam anta-gatam papam. So without being freed from sinful activities nobody can take to Krsna consciousness. The method is easy. You can get out of sinful activities. But don't commit again. If you think that "I shall ignite fire and pour water again," then what is the use of? Simply waste of time. So that should not be done.
