Yoga is not a Therapy
Yoga is discipline. It is an effort on your part to change yourself. Yoga is not a therapy. In the West many psychological therapies are prevalent now, and many western psychologists think that yoga is also a therapy. It is not! It is a discipline. And the difference is : a therapy is needed if you are ill, a therapy is needed if you are diseased, a therapy is needed if you are pathological. A discipline is needed even when you are healthy. Really, when you are healthy only a discipline can help then.
Therapies are for ill people. Therapies can help you to come to yoga, but yoga is not a therapy. Yoga is for a higher order of health, a different order of health – a different type of being and wholeness. Therapy can, at the most, make you adjusted.
Yoga is not therapy; yoga is not trying in any way to make you adjusted to the society. If you want to define yoga in terms of adjustment, then it is not adjustment with the society, but it is adjustment with existence itself. It is adjustment with the divine!
Patanjali's asanas, postures, are concerned not really with any kind of physiological training, but an inner training of being, just to be – without doing anything, without any movement, without any activity, just remain. That remaining will help centering.
