The seed of prayer is sown in heaven.
It pushes its stem toward the earth
and comes to grow there.
It produces an abundance of fruit.
Then, as it becomes seed once more,
it thrusts its way back to heaven.
~ Jukichi Yagi
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.
