I know that meditation can be very helpful in increasing general awareness, but I'm wondering, does it matter what kind of meditation is practiced? Up until recently I've just been sitting on the floor and focusing on my breathing. But I've just heard of something called "transcendental meditation", which apparently can only be taught by an instructor one-on-one. I'm going to an Intro session in a few weeks, and I may start practicing it regularly. But if my floor-sitting meditation is fine for lucid dreaming, I'd just as well stick with that, instead of going to all the meetings for TM.
