No one can be saved without divine light. Divine light causes us to begin and to make progress, and it leads us to the summit of perfection. Therefore if you want to begin and to receive this divine light, pray. If you have begun to make progress and want this light to be intensified within you, pray. And if you have reached the summit of perfection, and want to be superillumined so as to remain in that state, pray.
