My meditative practice, and the fact that I keep making progress, becoming more and more alive to and in love with reality. Ok, that sounds kind of lame, but the change in my consciousness really has been incredible. I don't know if that qualifies as religion, contemplation, or the quest for (self) knowledge... it's in between all three.
I don't feel like meditation is something that I hold onto like a comforting blanket though, it's more like it's eroding my need to hold on to anything.
Music is also a major support but it's kind of augmenting my meditative progress more than anything else.
Pot used to be a co-support but I don't really care about it much now that I'm in a better place.
