On page 64 of White Sail, Norbu writes of Wisdom Deity:

In mahayoga, it is called the immeasurable pervasiveness of purity because it is the boundless radiance of the expanse of awareness wisdom.

In the Christian tradition, this is represented by the Virgin Mary, whose love for God is so perfect, so pure, that she is elevated to the station of The Queen of Angels.  All the angels are described is brilliant, associated with fire.

What is being said in this passage from White Sail is that by annihilating dualistic grasping mind, the yogi or yogini achieves a boundless purity of limitless consciousness that is not conditioned by ego.  Everything becomes enlightened.  There is no duality, no expectation, no measurement, no analysis, no morality, no good or evil.  This doesn’t mean that there is no movement in the Wisdom Deity itself.  Far from it.  But in enlightenment, all arisings are simply seen as wisdom display, in other words, all is simply movement without the conceptions that are projected upon them by the dualistic grasping ego mind.
