The most subtle teachings must be abandoned along the way. The tantrika's courage is in letting go of teachings once they've been absorbed. Even the Tantras aren't worth any more than a skin abandoned on the stones by a molting snake. When one is constantly changing, there comes a day when the consciousness rests on nothing. Then awakening occurs.
All nature is subject to transformation.
An awakening that isn't in accord with the deep nature of things gradually becomes diluted. It's not enough to find a raw nugget. It's necessary to let life run over it until the gold dazzles the entire universe. Devi ate slowly. This way of absorbing herself in things extended to her every activity.
