So I just got this Dead Meadow album, got a great 70s psychedelia feel , liking the music so far a lot, but I was curious what the symbolism inside the album cover meant. Here it is:

Specifically the hand symbol and the thing on the robe (that sorta looks like the fantastic four emblem funnily enough ). Anyone know? Thanks. Everything else looks like it's taken from Revelation in the bible, but those two things I couldn't find references to.
