Yoga, as a restorative, support and preventative, can be a therapy to help us work at changing or anticipating the effects of problems and illness in our lives.
Here the approach must be different for each person as our potential will be affected by the problem, or the problem by our attitude towards working with it.
Also according to traditional Indian medicine those diseases that are chronic and cannot be cured by medicine alone can be helped by using Yoga techniques. So Yoga can support other forms of treatment.
Yoga texts also talk about the benefits of certain postures and breathing techniques.
Utilising these concepts it is possible, within a careful teaching situation and our wish to learn and help ourselves, to introduce practices that both respect the problems or illness and support our intention to reduce their negative effects in the future.
However, Yoga as a therapy also presumes that we are willing to accept responsibility for change within our own situation.
These three aspects of Yoga, power, self-inquiry and therapy are mutually supportive in helping to maintain physical health, psychological vitality and spiritual purpose within the commitment and challenges of life, work and relationships.
