The yoga is a complete subject giving insight to the participant and answer to a major question “Who Am I?” is found by the adept by faith & self discipline. The answer to this question is in eternity and beyond physical structure. It is therefore necessary to know the physical structure of the body. The structure of human body is so perfect that one may call it a miracle. All its organs work automatically and the body as a whole can remain healthy without any external aids, like medicines etc. What is required is to follow certain laws of nature and the rest would be taken care of by the body itself.

Just as a house is built with several types of big and small bricks, cement, lime and mud, in the same way the body of living beings is made up of certain ‘building blocks’. The only difference between the two is that while the blocks used in the body have life, those used in the building of a house are lifeless. These living units are called cells. These cells have many shapes and sizes-some are big, others are small, some flat, while others are round. But they cannot be seen with the naked eye.

To take another analogy, the body can be compared to a big state. As the functions of a state are divided into several departments and those departments are responsible for the functions assigned to them, similarly, there are several departments in a human body. Several body organs combine to make one such department. There is perfect co-ordination between one department and another, as well as within the organs of one department. If there is any disorder in this cooperative functioning, the body is unable to perform its functions properly. Yogasanas are practiced to keep this functioning in perfect order
