HATHA YOGA / KAVITA PILLAY
This literally means “union through the discipline of force”, is a school of Yoga that stresses mastery of the body as a way of attaining a state of spiritual perfection in which the mind is withdrawn from external objects. Hatha Yoga has grown in popularity in the West as a form of exercise that develops strength, flexibility, bodily relaxation, and mental concentration.
Yoga postures, while having many great benefits is not what Patanjali was referring to in his sutras. The purpose of asana is to enable one to rise above body-consciousness. A straight spine is necessary, for when meditating the energy must be allowed to rise up the spine freely. One may consider that they have mastered asana if they can remain completely motionless, with a straight, upright spine for three hours. Motionlessness will enable them to become aware of the inner energies in the body.
