When the whole consciousness is silent and tranquil, free from all becoming, which is spontaneity, then only does the immeasurable come into being. For, when the mind is still, reality, the indescribably, comes into being. So the mind must be simple, unburdened by belief, by ideation. And when there is stillness, when there is no desire, no longing, when the mind is absolutely quiet with a stillness that is not induced, then reality comes. And when that happens, it is a blessing.
The dark night of the soul refers to an extended period of acute purification that a spiritual practitioner undergoes immediately before making the final transition to deep spiritual awakening. It emphasizes purification and the act of letting go of what no longer serves after many lesser trials have been navigated.
