Jai Sri Ganesha,
The body of the man has been divided into five regions, Each region is represented be an element among the five mains,
Earth relates feet up-to knee, water relates region between knee and the naval, Fire rules the truth from naval up to neck, air from neck to middle of eyebrows,
And sky exist with its truth in between eyebrows to to Brahmaranddhra,
Man must make up his mind in tuning with to calm self for the truth of meditation,
May Lord bless all,
Thanks please
