Temples and monasteries should be constructed for the preaching of spiritual consciousness or Krsna consciousness, not to provide free hotels for persons who are useful for neither material nor spiritual purposes. Temples and monasteries should be strictly off limits to worthless clubs of crazy men. In the Krsna consciousness movement we welcome everyone who agrees at least to follow the movement's regulative principles — no illicit sex, no intoxication, no meat-eating and no gambling. In the temples and monasteries, gatherings of unnecessary, rejected, lazy fellows should be strictly disallowed. The temples and monasteries should be used exclusively by devotees who are serious about spiritual advancement in Krsna consciousness.
