You must make sure that all of these devotees are following the regulative
principles very nicely. Everyone must rise early, take bath attend mangala arati, chant at least 16 good rounds, attend class, and follow the four regulative principles strictly. If these things are lax, then there is no question of spiritual life. Any one who does not accept these things staunchly will have to fall down. You must teach them by your own personal example otherwise how will they learn. If you are loose in your habits, then everyone in your temple will also be loose in their habits. So, as one of my elder disciples, be strong. Do not deviate and you will be blessed.
