Regardless of your present habits, whether pure or impure, we invite you to please join us in chanting Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare, and perhaps visit a center for Krishna consciousness to taste some Krishna prasada and hear more as well. In such harmless activities there can be no loss, and you may find the greatest gain.
