KAYENDRIYA SIDDHHI ASHUDDHHI KSHAYAT TAPASAH
WHEN TAPA OR ASTERITY IS PERFECTED IMPURITIES OF BODY AND ORGANS IS
DESTROYED AND THEY ARE PERFECTED
When one does the austerity or what is here called TAPAH , then he develops the purity of the body and it's organs . So Let us first see what is TAPAH , or austerity. It could be as simple as fasting on certain days , which is very common in many religions, to strict dietary restrictions. Not eating certain foods all the time is also part of austerity. One could put control various desire or needs, is part of austerity. So when we are IN CHARGE of our various organs and MIND and not the other-way around , i.e. they are controlling our behavior, then that is austerity. So when we decide the restrictions on what we eat or drink or control outer temperature or here certain music and avoid other , etc this all is part of our training our mind and controlling the organs . But this is not just superficial control . So it is not enough that we don't eat certain food , but we don't have any desire to eat it or no matter what we are eating our reaction to eat is same .
So when this perfected by every organ in our body we get some powers or Sidhhi . Again with bodily control will lead to purification of body . So Yogi can think much more clearly and sees better , hearing is great and every organ and mind works at it's peak . So one has to treat or feel same under any condition , No matter what we are eating or listening or seeing , we should have no attachment to it . Then only this can be achieved.
