The practice of relaxing the muscles of the body will bring rest to the body and to the mind also. The tension of the muscles will be relieved. People who know the science of relaxation do not waste any energy. They can meditate well. Take a few deep breaths and then lie down flat on your back as in Savasana. Roll on to one side and then relax as thoroughly as you can do. Do not strain the muscles. Roll on the other side and relax. This is naturally done by all during sleep. There are various exercises in relaxation, for the particular muscles of a particular part of the body. You can relax the head, the shoulders, the arms, forearms, wrist, etc. Yogins know the science of relaxation thoroughly. When you practise these various relaxation exercises, you must have the mental picture of calmness and strength.
RELAXATION OF MIND
Mental poise and calmness may be brought about by the eradication of worry and anger. Fear really underlies both worry and anger. Nothing is gained by worry and anger, but on the contrary much energy is wasted by these two kinds of lower emotions. If a man worries much and if he is irritable, he is indeed a very weak man. Be careful and thoughtful. All unnecessary worries can be avoided. Relaxation of the muscles reacts on the mind and brings repose to the mind. Relaxation of the mind brings rest to the body also. Body and mind are intimately connected. Body is a mould prepared by the mind for its enjoyment.
Sit for 15 minutes in a relaxed and easy comfortable position. Close your eyes. Withdraw the mind from outside objects. Still the mind. Silence the bubbling thoughts. Think that the body is like a coconut shell and you are entirely different from the body. Think that the body is an instrument in your hands. Identify yourself with the all-pervading Spirit or Atman. Imagine that the whole world and your body are floating like a piece of straw in this vast ocean of Spirit. Feel that you are in touch with the Supreme Being. Feel that the life of the whole world is pulsating, vibrating and throbbing through you. Feel that the ocean of life is gently rocking you on its vast bosom. Then open your eyes. You will experience immense mental peace, mental vigour and mental strength. Practise and feel this.
