Kumara Vaishnava Sampradaya - Commentary
Lord Krishna uses the word niyatma meaning consistency  and  refers  to  the
regulated performance of prescribed Vedic activities as  a  matter  of  duty
according to varnasrama the position and status one is situated in  society.
The words sanga-rahitam means free from attachment and egoism  that  one  is
the doer. The words araga-dvestha mean devoid of attraction to  fame,  power
and an enjoying nature as well as void of aversion for defeat,  failure  and
obscurity. Acts performed without a mentality  of  attraction  and  aversion
are without vanity and ego and bereft of desire for  phala  or  rewards  and
are firmly situated in sattva guna the mode of goodness.
