Your body is nothing but the manifestation of the 5 elements of the nature proper proportions
"WATER, EARTH, FIRE, SPACE & ETHER"
If you can take care of these elements and treat them properly, they will start obeying you and you can become master of your system…!!
Sadhguru explains in an elegant way here… the prakriya (method) of Bhootha Sudhi (Cleansing elements ) and Bhootha Siddha (Mastering the elements)
