Although the candidates for initiation takes some vows, these vows should be accepted on the strength of their faith in the power of the Lord's Holy Name. Each one of them should think, “I will be able to maintain these vows only by maintaining my firm faith in the Holy Name of the Lord and my firm faith in those instructions which I will receive in relationship to the Holy Name." In that consciousness, we can maintain our vows; otherwise, there may be difficulties.
