Good health is the greatest asset. Without good health one can hardly expect success in any walk of life. To keep up good health, there are numerous modern physical culture systems designed to develop the muscles. The physical culturist develops them by mechanical movements and exercises. In such physical exercises, there is a fast movement of the muscles resulting in the rapid functioning of the heart and lungs. The practitioner becomes exhausted very quickly. There may also be anxiety, psychological tension and fear. Some exercises develop the chest and the arms only, which becomes lopsided and results in disharmony in the personality.
In Yogic exercises, there is harmonious development of all the muscles of the body, internal organs, nerves and the frame. There are no rapid movements and hence there is no waste of energy. In Yoga exercise movements are gentle and rhythmic. On the other hand, they conserve energy.
The three important organs viz., heart, lungs and brain with its cerebro-spinal system, are kept in a healthy condition by regular practice of a few important Asanas and one or two breathing exercises. Sound functioning of the organs depends upon good healthy nerves. The tripod of life are the brain, heart and the lungs. The heart and the lungs are under the control of the brain. These three important organs along with the cerebro-spinal system are kept in a healthy condition by regular Yogic exercises.
If the muscles are not given proper exercises, they will tend to contract and there will be stiffness and heaviness in the body. Blood circulation and nerve force will consequently be impeded. Their malfunctioning will disturb the organs. Some of the Yogic exercises concentrate on the development of the muscle also, consistent with the development of other parts as well.
These Yogic exercises are both preventive and curative in their nature. On the whole, they prevent diseases attacking the body by maintaining the natural health. Some exercises also cure existing diseases like cold, cough, constipation and gastric troubles.
Some Yogic exercises involve forward and backward motions, others help the lateral movement of the spine. Some clean the lungs, throat, etc. Thus the body as a whole is developed, toned up and strengthened. The entire body becomes flexible, thereby preventing stagnation of blood in any part of the body. Another unique feature of these exercises is, however, their influence upon the endocrine system of glands, the ductless glands as they are called. The malfunctioning of the thyroid, pituitary and pineal glands is corrected by a course of selected postures. Besides all this, some the exercises have great effect upon man's mind, his power of concentration and memory. They also wake up his dormant spiritual faculty. The Prana or the vital force is externalised in modern physical exercises, whereas the Yogic exercises make the Pranic current flow inwards. These Yogic exercises help to improve the health by regulating the functioning of the internal organs. Their regular practice brings to every practitioner, good health, longevity, strength, vim and vitality. By practising the Yoga Asanas regularly with care and caution, the personality as a whole will become pleasing and attractive.
This system is simple, exact, efficacious, economical and capable of being practised without any extraneous help when once a preliminary knowledge about it is obtained.
