I think illusion is one of the most interesting things that I've found to think about. Just look at yesterday, and what you were doing, and how important it was, and how nonexistent it is now! How dreamlike it is! Same thing with tomorrow. So where are we living?
Yoga is ideal for calming the mind and harmonizing with nature. Plus, since this meditation consists of listening to what's taking place in the instant, it brings the mind into the present, where the body resides, producing unification of mind and body.
