I love yoga!
Of course, *yoga* is a catch-all word referring to the
postures of yoga: asana. It's just one of the actual 8 parts (or limbs) that make up the whole philosophy of *yoga,* which includes the yamas, the niyamas, and pranayama (the breathing exercises). Concentration and meditation are also part of *yoga.* All together, this 8-fold path of yoga is simply there to offer suggestions for living a better life through yoga.
All that aside, going through my routine of asana is the highlight of my day! I started with Kundalini yoga but practice more hatha style these days. The physical part is to help ready the mind for meditation and inner perceptual awareness. It's all quite lovely, if you just let yourself go with it.
