Furthermore, in the Mañjuśrījñālamahātantra, it is said:
If a disciple who has become deluded, despite having received the initiations and having fully completed the preparatory and main practices from a Vajra Master, transgresses the root and branch samayas, the foolish disciple must confess them. If one does not confess them and the time passes, one will experience suffering to the extent of being able to remove the water of the great outer ocean with a single hair; this is what is known as the Vajra Hell.
