As a Yoga Therapist, focus on increasing people's quality of life not on curing diseases.
Another important aspect is that the masters taught us to move from a deeper source,not just from muscles and joints.
Anybody can breathe. Therefore anybody can practice yoga.
It is not enough to jump if you want to reach the sky.
Yoga is both the movement toward and the arrival at a point.
The practice of yoga only requires us to act and to be attentive in our actions.
