Hatha Yoga
Hatha Yoga, also called Hatha Vidya, is a system of Yoga introduced by Yogi Swatmarama, a sage of 15th century India, and compiler of the Hatha Yoga Pradipika. In this treatise Swatmarama introduces Hatha Yoga as preparatory stage of physical purification that the body practices for higher meditation. The Asanas (postures) and Pranayama (breathing) in Raja Yoga were what the Hindu Yogis used to physically train their body for long periods of meditation. This practice is called shatkarma.
Traditional Hatha Yoga is a holistic yogic path, including moral disciplines, physical postures (asana), purification procedures (shatkriya), poses (mudra), yogic breathing (pranayama), and meditation. The Hatha yoga predominantly practiced in the West consists of mostly asanas understood as physical exercises. It is also recognized as a stress-reducing practice.
Hatha represents opposing energies: hot and cold (fire and water, following similar concept as yin-yang), male and female, positive and negative. Hatha yoga attempts to balance mind and body via physical postures or “asanas”, purification practices, controlled breathing, and the calming of the mind through relaxation and meditation. Asanas teach poise, balance and strength and are practiced to improve the body’s physical health and clear the mind in preparation for meditation in the pursuit of enlightenment.
Hatha Yoga consists of six limbs focused on attaining Samadhi. In this scheme, the six limbs of Hatha Yoga are defined as Asana, Pranayama, Pratyahara, Dharana, Dhyanaand Samadhi. The basic text of Hatha Yoga is Hathapradipika by Svatmarama, a grand disciple of Sahajananda. The signs of success in hatha yoga are slenderness of the body, cheerful face, hearing mystical sound, bright eyes, sense of well-being, control over the bindu, increase in gastric fire and purification of the nadis.
