Whats so fascinating to me about PKD is that he taps into this rich, long, history of esoteric philosphy and practices and connects dots between ideas from disperate traditions. Not in the same way theosophy does- he seems to be more lucid and consistant.

This idea he has of wickedness being some kind of abscess in an otherwise perfect hermetically sealed bubble, and that the second coming of christ would be an event in which the evil is removed from the pure buble---- it explains concepts in christianity with concepts from other world religions and does so in an exceptionally vivid fashion. Quite terrifying.
