The initiates are vowing before the Deity, the Spiritual Master, the fire, the Vaisnavas, and the Supersoul to follow the four regulative principles: namely no illicit sex-life, no intoxication, no meat-eating, and no gambling, and to chant daily at least 16 rounds of japa. In this way if they hold firmly to this principle there will not be any obstacle to their steady progress in Krishna Consciousness, and one can go back to home, back to Godhead in this lifetime.
