The most important benefit of  yoga is physical and mental therapy. The aging process, which is largely an artificial condition, caused mainly by autointoxication or self-poisoning, can be slowed down by practicing yoga.Regular practice of asanas, pranayama and  meditation can help such diverse ailments such as diabetes, blood pressure, digestive disorders, arthritis, arteriosclerosis, chronic fatigue, asthma, varicose veins and  heart conditions.

According to medical scientists,  yoga therapy is successful because of the balance created in the nervous and endocrine systems which directly influences all the other systems and organs of the body.  Yoga acts both as a curative and preventive therapy. The very essence of  yoga lies in attaining mental peace, improved concentration powers, a relaxed state of living and harmony in relationships.

More importantly, yoga is extremely effective in:
    
Increasing Flexibility – yoga has positions that act upon the various joints of the body including those joints that are never really on the ‘radar screen’ let alone exercised.

Increasing lubrication of the joints, ligaments and tendons – likewise, the well-researched yoga positions exercise the different tendons and ligaments of the body.

Massaging of ALL Organs of the Body – Yoga is perhaps the only form of activity which massages all the internal glands and organs of the body in a thorough manner, including those – such as the prostate - that hardly get externally stimulated during our entire lifetime. Yoga acts in a wholesome manner on the various body parts. This stimulation and massage of the organs in turn benefits us by keeping away disease and providing a forewarning at the first possible instance of a likely onset of disease or disorder.
