807) Whether I know I must observe the Regulative Principles! Taught by Srila Prabhupada!
————– Just like we have asked our students to finish sixteen rounds chanting minimum. Sixteen rounds is nothing. In Vrndavana there are many devotees, they chant 120 rounds. Like that. So sixteen rounds is the minimum. Because I know in the Western countries it is difficult job to finish sixty-four rounds or 120 rounds, like that. Minimum sixteen rounds. That must be finished. Tat-tat-karma-pravartanat. This is the direction. Observing the regulative principles. In this way, we must be abiding by the direction of the spiritual master and the sastra. Then rest assured. Success if guaranteed. ———–
