Bikram is hot. Very hot. They keep the room around a hundred degrees, I think. And it's a set series of poses, held for relatively long periods of time. Some poses I knew, some I didn't; some were easy, some were freakin' impossible (standing head-to-knee, anyone?!).
But after the first few minutes, I ceased feeling the heat around me and grew conscious of it building inside me - an incredible wellspring of energy like molten lava, accessible by pure will alone.
So yeah. I think I liked it. I'll have to see how I feel tomorrow ;)
