Jai Sri Ganesha,
Body of man is unique in itself,
Five elements rules the five regions in it,
Region under the knee represent the truth of earth in gross mode, above knee and under navel region belongs to water, from navel to neck is the truth of fire, air pitched at region from neck to eye brows, above eye brow, the region ruled by the truth of sky,
Though earth to sky exist from hair of head to nail of foot yet distinction define the chapter on the bases of its core truth which relates the cause respective for the fair function of body,
May lord bless all,
Thanks please
