As for the dark night of the soul and whatnot, yes, that is related.

It's kind of both an event and a process.

The "dark night of the soul" I describe as the period during which one is stripped of that which they never truly were...stripped of their "earthly trappings of the personality".

It corresponds with "salvation", i.e. disSOLVe...SALVation.

It corresponds with the "possession" associated with "djinn" but the possession is 180 degrees the opposite of what is really happening. It's a dispossession of the "earthly trappings of the personality".

It corresponds with the hidden Sephirah, da'ath, on the Tree of Life of Kabbalah.

It corresponds to the Phoenix rising from its own ashes.

It corresponds to "solve et coagula" as well.

For me, the dark night of the soul lasted years because I didn't know what I had experienced initially. It took me nearly 53 months to feel like I had a thread to tug upon. Medicine Man gave me that.
