Through his sovereign yogic power the gross aspect of reality is, for him, devaluated; for he can produce the subtle, fluid forms of the inward state of vision whenever he likes, fix them and retain them as long as he requires, and after that, again according to his wish, come temporarily back into touch with the exterior world.

The components of the syllable are A, U, M.62 81 Bhagavad Gita 4. 7.
52 As will immediately appear, the silence that follows and surrounds the syllable is the fourth component. The identification of these three
