If you are interested, here is a link to a podcast about Jack Parsons. The podcast doesn't talk about Twin Peaks directly, it deals with Parsons, Crowley, sex magic, and so on.

I have posted this before (but can’t find it) but I find it quite fascinating that in “The Secret History of Twin Peaks”, that when Jack Parsons is killed in the explosion, one of his arms is atomised and not found. This must be relevant to MIKE, the one-armed man.
