Yoga School of Philosophy
Freedom could be attained by practicing self-control (Yama), observation of rules (niyama), fixed postures (asana), breath control (pranayama), choosing an object (pratyahara) and fixing the mind (dharna), concentrating on the chosen object (dhyana) and complete dissolution of self, merging the mind and the object (samadhi). Yoga admits the existence of God as a teacher and guide.
