One basic assumption of the Yoga Sutras is that the body and the mind are part of one continuum of existence, the mind being more subtle than the body. This is the foundation of the yogic view of health. The interaction of body and mind is the central concern of the entire science. It is believed that as the body and mind are brought into balance and health, the individual will be able to perceive his true nature; this will allow life to be lived through him more freely and spontaneously.

Yoga first attempts to reach the mind, where health begins, for mental choices strongly affect the health of the body. Choices of food, types of exercise, which thoughts to think, etc. all affect the body. As practiced traditionally in India, yoga includes a set of ethical imperatives and moral precepts, including diet, exercise, and meditative aspects. In the West, yoga focuses primarily on postures (gentle stretching exercises), breathing exercises, and meditation. Yoga is frequently used in Western medicine to enhance health and treat chronic disease as well as stress.

Yoga therapy begins with relaxation. Living in an age of anxiety, we are often unconscious of our tensions. We are often depressed, tired, and an easy victim of diseases. There are a number of reasons for our stressful life. Often it is lack of rest, anxiety, tension and fatigue. These are constantly draining our health energies continuously. Thus, the first priority is to get us into a relaxed state. Yoga employs asanas, pranayama (breathing exercises) and meditation and/or visualization.
