The ancient masters have highly developed the science of postures. Unfortunately, just a fragmented knowledge about this wisdom reaches our times through the Hindu people, but its true meaning is not grasped because currently people makes the mistake of analyzing everything separately and do nor look for relations with the Unity.
A right placement of the spinal column depends entirely upon a higher perfection grade in postures. Many ancient postures have been devised in such way that during their practice are forcing the spine to its right position.
In natural human postures, the spinal column should form a line with very light undulations, but usually in most men convexity more or less marked in their backs can be found on the upper area of the spine (chyphosis).
Once you expanded the movement of the spine with exercises of straightening, you should practice the following exercise, which makes your spine more flexible and dynamic, and that at the same time is the synthesis of every natural movement of the spine.
