One needs to 'see' and 'assimilate' the real meaning of 'Nirpekshata' (indifference). There is one nirpek... which is of a person who doesn't like someone, such a fellow is also indiff... but this is not the nirpek... we cherish, because such an attitude is ego-centric and prompted by conditionings. In such a nirpek... there is lack of sensitivity; and the nirpekshata which is ishta is the one with profound sensitivity. 'See' the meaning of real nirpe.. and let it be a quality of your heart. This alone will facilitate us to see the anitya as anitya and nitya as nitya, in fact such a nirpek... implies this viveka alone.
