Tapasvins hold Prakriti in disdain, because everything in nature is mortal. They seek immortality. In nature, everything is limited by space and time and restricted by form. The Tapasvin wants to break free from all limitations, expand into infinity, achieve what is called Siddha, the ability to acquire whatever he desires, not be fettered by gravity. And so the Tapasvin seeks to fly in the air and walk on water, expand and contract his size, change his shape. He seeks independence from nature. Withdrawing from nature is the first step in this process.
