Was an Esalen denizen for a good while. I know someone who sat-in as he was at work (there were always many persons about). Took guts to sit in that seat. (My friend never did). Long ago read, In and Out of the Garbage Pail and maybe thumbed your ref.
(A friend and I -though not ever 'regulars'- put on Esalen's First 'computer workshop' - for Writers, natch. With a bunch of borrowed Osborne1s / WordStar. Some never got the concept of "a floppy disk" throughout; others went on within minutes, to write a short story and explore the Possibilities of: an endless supply of White-Out for emending, repositioning! Word-processors du jour like Wang - cost Thousands.. and shortly died, too)
Not much in the way of metaphysical answers from Fritz, but certainly one of the Best anti-BSers extant (once). If you *really* wanted to work on Your Hangups (through with blaming others) - Fritz was your cat-o-nine tales Guy.

(regret I never 'saw' him; in days he was around there, I wasn't)
Edit - as to Jung: yes of course; omit the metaphysical, and all ya gets is another Cookbook. That doesn't make it any easier to deal with *That Idea* in (even special) language. But I keep coming back to notice what he must have grokked, to even try..
