Yeah. One of the smartest things I heard is from Huston Smith. Somebody asked him the relationship between religion and spirituality. He said, "Religion gives spirituality historical traction."

I'm pretty antireligious, so I get why bobsgame was creeped out by the historical-traction aspects of their practices. (People tried to force me to be Christian in my teens, so I've got a bucket of fuck-you ready whenever I feel the slightest religious pressure.) And if one doesn't feel safe, one should get up and go. But many people teach meditation in ways that are either low on religion or consciously eschew it.

I'd add that it is worth playing with some of the practices regardless. Chanting, for example. The mock religion "Church of the Subgenius" have redone the hare krishna chant to use the Three Stooges:

    Larry Curly Larry Curly
    Curly Curly Larry Larry
    Larry Moe Larry Moe
    Moe Moe Larry Larry

Meditative chanting like that (which, for clarity, I do at home, not in somebody else's temple) is a really interesting experience. It made me more open to occasionally joining in with other people's religious practices; knowing the experience I was less worried about getting sucked in.
