1) Mountain posture. Where you stand in perfect alignment and try to keep the arches of your feet off the ground to allow the old prana to circulate around. Never mind the hippy stuff, this is great if you have pointy out feet and flat arches, helps you re-align your entire body, aiding the muscle memory and the best thing - Not a damn orthotic device needed!
2) The relaxation afterwards. You lie down, spread your legs and arms out and "relax" the your body starting from your toes and working up to your head. Wonderful after a really hard effort. I do this after a bodyweight workout and try and visualise my muscles repairing themselves, very good stuff.
I love yoga, but I have no time for the bollocks side of it, all the netty pots and hopi candles etc.
