yama—moral discipline comprising nonharming (ahimsā), nonstealing (asteya), truthfulness (satya), chastity (brahmacarya), and nongrasping or greedlessness (aparigraha) 2. niyama—self-restraint comprising purity (shauca), contentment (samtosha), asceticism (tapas), self-study (svādhyāya), and devotion to the Lord (īshvara-pranidhāna) 3. āsana—posture (specifically for meditation) 4. prānāyāma—breath control 5. pratyāhāra—sensory inhibition 6. dhāranā—concentration 7. dhyāna—meditation, or sustained and deepening concentration 8. samādhi—ecstasy, or merging in consciousness with the object of meditation Together the eight limbs lead practitioners out of the maze of their own preconceptions and confusions to a sublime state of freedom. This is accomplished through the progressive control of the mind (citta). Beyond the highest ecstatic state lies the freedom of the transcendental Self, which is the pure Witness (sākshin) of all mental processes. For Patanjali, Self-realization is kaivalya, or the “isolation” or “aloneness” of that transcendental Witness. The many free Selves (purusha) all intersect in infinity and eternity. Enlightenment, or liberation, consists in simply waking up to our true nature, which is the transcendental Spirit, or Self. HATHA-YOGA The word hatha means “force” or “forceful.” Thus Hatha-Yoga is the “forceful Yoga” or “Yoga of Force,” meaning the Yoga of the inner kundalinī power. This branch of Yoga, which is particularly associated with Matsyendra Nātha and Goraksha Nātha, two perfected masters or siddhas, is a medieval development arising out of Tantra. It approaches Self-realization through the vehicle of the physical body and its energetic (pranic/etheric) template. In the first instance, Hatha-Yoga seeks to strengthen or “bake” the body so that practitioners have a chance to cultivate higher realizations. Secondly, it means to transubstantiate the body into a “divine body” (divyadeha) or “adamantine body” (vajra-deha), which is endowed with all kinds of paranormal capacities. Thus, the disciplines of Hatha-Yoga are designed to help manifest the ultimate Reality in the finite human body-mind. Sri Aurobindo put it this way: The chief processes of Hathayoga are āsana and prānāyāma. By its numerous Asanas or fixed postures it first cures the body of that restlessness which is a sign of its inability to contain without working them off in action and movement the vital forces poured into it from the universal Life-Ocean, gives to it an extraordinary health, force and suppleness and seeks to liberate it from the habits by which it is subjected to ordinary physical Nature and kept within the narrow bounds of her normal operations. . . . By various subsidiary but elaborate processes the Hathayogin next contrives to keep the body free from all impurities and the nervous system unclogged for those exercises of respiration which are his most important instruments.1
