When I first came across yoga at the age of 20 I was deeply moved, not so much by the discipline that kept my body in good shape but by the realisation that yoga can open a door to a new world of understanding and experience. I had studied philosophy and found it a mere intellectual exercise, like reading a travel brochure, but in yoga I found a way of actually going to the foreign places. Yoga can bring insight and transformation to your whole being if taught with a deeper understanding of Indian philosophy. However not much insight or transformation will occur if yoga is only practiced and taught as muscle stretching. As a teacher of 17 years, and running my 4th diploma course, I have tried to refine my approach to the deeper meaning of yoga philosophy on the mat.
