Crossing the Abyss
Barry diving into the tar pit reminded me of what Crowley called "crossing the abyss". I guess that goes back to "Golden Dawn"-mythology, and probably farther back, already.
It is basically the last step in the path to enlightenment, if you want to call it that. A step that means the destruction of the self. You surrender everything and your "karma" or something determines how you emerge on the other side. As a "brother of the left-hand" (black, "evil") and "right-hand path" (white, "good").
So I guess Barry was a brother of the left-hand path ;)
I will now end this debate with you.
