The human body is the most dignified and the most complicated mechanism in the whole world. It has been formed in such a way that it is very essential to keep it constantly active and in perfect order. The yogic exercises help a lot in this respect. The desired results of sadhana (spiritual exertion) can be obtained by maintaining the activity and health of the body. These physical exercises are an important part of the Preksha technique with a view to keep the body active and in perfect order. Looking to the conditions of place, time and society of present world, it is growing difficult day by day for every body to devote much time in yogic postures and exercises. If one has no problem of time, the factor of'place' creates difficulties for him. The city life has taken a person away from nature. He has neither the land for putting in physical labour nor pollution free environment (open space for walking where he can inhale uncontaminated oxygen) and develop a healthy physique. He has to traverse daily the crowded paths in narrow habitations: He has to live in small flats with his whole family. In addition to this; man has adopted such an artificial life that inspite of his ardent desire he cannot devote time in physical postures, Preksha meditation and other allied techniques.
