Yoga is a systematic practice, of physical exercise, relaxation, breath control, diet control, positive thinking and meditation, aimed at developing harmony in the body, mind and environment. It is a physical, mental, and spiritual practice or discipline which originated in India over 5,000 years ago. The word yoga was first mentioned in the oldest sacred texts, the Rig Veda.
There are two components in yoga, the philosophy and the practice, with each informing and refining the other, in order to forge a unity of body-mind spirt. Both the practice and philosophy of yoga have a rich depth of knowledge and a long history and are both essential aspects of yoga.
