Body as fruit of karma has its own time scale

Eventually, the question is how to cleanse the mind of its मल mala or impurity. Of course the Yoga SUtra says this should be done by tapas. But this body obtained by the mind as a fruit of past karma has its own time scale. Why try to strive for a perfect body or divya deha, when ultimately the body is merely a vehicle that has to be transcended?

But if one's true nature as the Self is believed in on the basis of श्रद्धा (shraddhA, which is faith in the words of vedAnta and the Guru) and if it is known through even one direct experience to be beyond time, then turn the mind inward away from the "I am the body" idea and ask "Who is this I?"

This naturally leads inward through all the panca koshas to that which is beyond the koshas and also their very substratum: the Self.
