"Iyengar Yoga is firmly grounded in the ancient Indian art of yoga. More than 2,500 years ago, in The Yoga Sutras, Patanjali wrote about Astanga Yoga, the eight-limbed path towards spiritual fulllment. Iyengar Yoga addresses this journey from a perspective which is practical, experiential and intensely personal.
Yoga is, at its most simple, union -- the union of mind, body and spirit. In Iyengar Yoga, this search for union begins with ongoing practice of the yoga asanas (postures) with a focus on exact alignment. In time students learn to penetrate beyond the outer physical layer to the inner kosas (layers) of mind, energy and spirit.
Mr. Iyengar has said that there is no Iyengar Yoga -- only Patanjali's Yoga. It is his unique perspective that the yoga asanas and Pranayamaa (the control of the breath) can be a template to explore, evaluate and experience each of the other limbs The journey begins with the two limbs ofAstanga Yoga, Yama and Niyama, the yogic guidelines for personal and ethical conduct. Asana can even carry us through to the higher limbs of yoga, including Pratyhara (withdrawal of the senses), Dharana (concentration) and Dhyana (meditation), and point the way towards Samadhi, the complete freedom at the end of the yogic journey."
