Physical aspects (Anatomical): (That which is perceived through the senses)
Construction of the body (anatomical) is to be understood prior to learning the effect of Yoga on it. The physical body has five sensory organs: eyes, ears, nose, skin & taste. All of these are located in the face except the skin. The sensing ability of eyes, ears & nose are limited in terms of distance, the intensity of light, sound & smell.
The five basic feelings of light, sound, smell, taste & touch are related to five elements of creation which are fire, ether(space), earth, water & air.
