Guru maharaj: If one is initiated and breaks the principles, they are guilty of one of the offences to the holy name – disrespecting the order of the spiritual master. So there is no higher atonement than devotional service. So in that case one should repent for their misdeed and then again take up the practice of devotional service, as sincerely as possible, and gradually they can regain their status. But of course they have ceased their progress for some time, but they can start again and there is no other way recommended by the shaastras.
