In order to achieve perfect relaxation, three methods are used by yogis: Physical Relaxation: We know that every action is the result of a thought. Thoughts take form in action. Just as the mind may send a message to the muscles ordering them to contract, the mind may also send another message to bring relaxation to the physical body. The practice of auto-suggestion during final relaxation uses this technique.
Mental Relaxation: When experiencing mental tension, one should breathe slowly and rhythmically for a few minutes. The mind should follow the breath. If at any point, the mind becomes distracted, it should gently be brought back to the flow of breath. Soon the mind will become calm and you may experience a floating sensation.
Spiritual Relaxation: However much one may try to relax the mind, all tensions and worries cannot be completely removed until one reaches spiritual relaxation. As long as a person identifies with the body and mind, there will be worries, sorrows, anxieties, fear and anger. These emotions, in turn bring tension. Yogis know that unless a person can withdraw from the body/ mind idea and separate him/herself from the ego-consciousness, there is no way of obtaining complete relaxation. The yogi identifies him/herself with the all-pervading, all-powerful, all-peaceful and joyful Self, or Pure Consciousness within. This ability comes with the knowledge that the source of all power, peace and strength is in the Self, not in the body. We tune to this by asserting the real nature, which is "I am that pure Consciousness or Self." This identification with the Self completes the process of relaxation.
