Anger having failed to shake loose the secrets and Mysteries, the seeker turns to bargaining. Surely the secrets can be found in a book somewhere. Or maybe some other path has something equivalent to the Mysteries, without requiring the tests leading up to and including initiation. Or maybe someone will be pursuaded to leak the secrets. Bargaining, even when the seeker finds everything he seeks, in books or from informants, fails for this reason.
Anger burns itself out eventually.
Without the energizing nature of this emotion, the seeker moves into depression. The training period is long, and the process of finding a teacher was equally long. Or maybe the teacher continues to elude the seeker. Here we have the Samhain of the seeker's quest, the time when the light is fading and all hope is dying. The seeker has entered the dark night of the soul.
