"If Ajamila's very first uttered Name already burned up all his sins, why did he sin again afterward?" Gurudev answers with an image: sin after the Name is like a snake whose venomous fangs have been pulled out. It still raises its head, still lunges and bites — out of old habit. But there's no more venom in that bite, it doesn't kill. So it is with your old tendencies: they may still twitch and pull as before — but the Name has already removed their deadly sting. Don't be frightened when the habit stirs again, and don't think the Name hasn't worked.
