In the modern world the international problem is not poverty, drugs or fear of war; it is tension and only tension. A high percentage of people remain in a state of tension and frustration. This continuous level of tension in the body, mind and emotions predisposes the individual towards psychological and psychosomatic disorders. Modern psychology as well as yogic philosophy believes in three kinds of tension -muscular tensions, emotional tensions and mental tensions - which can be progressively released through the systematic and regular practice of yoga nidra. Each of the body parts has an existing centre in the cerebral white matter. The sequence of rotation of awareness in yoga nidra is in accordance with the map in the cerebral white matter of the brain.
