1. Four regulative principles and sixteen rounds

    Now you must agree to very rigidly follow the rules and regulations, i.e. chanting sixteen rounds of beads daily, rising early and attending Mangala Arati, observing the four principles, attending the classes, eating only bhagavata prasadam as well as working under the instruction of my representatives, such as your GBC representative and Temple President, and if you follow this procedure very strictly then your life will be glorious and you will go back to Home, back to Godhead, this I can guarantee.
