Patanjali's Eight Limbs of yoga practice are:
(1) Yama (The five "abstentions"): violence, lying, theft, (illicit) sex, and possessions
(2) Niyama (The five "observances"): purity, contentment, austerities, study, and surrender to god
(3) Asana: Literally means "seat", and in Patanjali's Sutras refers to seated positions used for meditation. Later, with the rise of Hatha yoga, asana came to refer to all the "postures"
(4) Pranayama ("Breath Control"): Control of prāna or vital breath
(5) Pratyahara ("Abstraction"): Reversal of the sense organs
(6) Dharana ("Concentration"): Fixing the attention on a single object
(7) Dhyana ("Meditation"): Intense contemplation of the true nature of reality
(8) Samadhi ("Liberation"): Super-conscious state of enlightenment
