The fact that regular yoga practice helps prevent many common ailments is proof that yoga is in addition to, not instead of other forms of health initiatives. So it should really be identified as a complementary discipline, rather than an alternative science. Think about it - what is so alternative about stretching that will not allow for a peaceful co-existence with other forms of fitness and preventive healthcare? Yoga is quite simply a self contained discipline that involves breath, focus, diet, relaxation techniques without excluding other forms of preventive healthcare. Yoga helps prep mind, body, spirit in tandem harmony. It includes all forms of physical and mental discipline, and explores spiritual terrain at an individual pace.
