There is two things: there's Krsna and there's sex life. So if you want to have Krsna, one must be above illicit sex life. That requires some strength. So you have to impress upon them that following these rules and regulations, especially by chanting Hare Krsna, one will become strong. Unfortunately, we have no taste for this chanting. This is our misfortune.
