The natural state burns away all Karma. Nirvikalpa Samadhi also burns Karma but unless you reach Sahaja–the spontaneous and easy living in day to day life–living without desires and fear–you can’t burn away all reactions. You come out of all exalted states which aren’t Sahaja and then everyday worries and fears catch hold of you. When the natural state dawns–the deletion of reactions becomes rapid and ultimately immediate in such a way that everyday life sinks below consciousness–i. e. you don’t get too concerned with mind stuff–in fact it becomes mostly difficult to bring about thoughts but all situations which need response are dealt with intelligence. Since reactions are created in being active before awakening–non-doing is needed for gaining renegade state–thereafter non doing becomes spontaneous and no matter what you do you do nothing and nothing ever goes WRONG!
Liberation is freedom from wrong ideas about oneself–because world is merely a reflection of it. When there is no fear or desire left and you consider yourself the world–you are accepted and you accept everything–flowing with life at ease. Easy is right and right is spontaneous. The noble virtue of non-doing burns away all reactions giving the ability to meet situations head-on.
