The Black Sun
This is the dark time in the work: searching for light in the underworld. In Alchemy it is known as blackening. We have found the prima materia, but are utterly lost. We are in the unconscious mind & don't know where we are, nor where to go. We must keep going, or lose all hope. This is the hardest work for the soul; we now use the vessel to distill all the elements present to see if they will produce the solution!
