Rudra Vaishnava Sampradaya - Commentary




Thus the tapah or austerities performed through the  physical  body,  speech
and  the  mind  have  been  delineated  by  Lord  Krishna.  These  threefold
austerities when practiced without any desire  for  reward  or  compensation
with great faith and steadfast determination by those devoted to  bhakti  or
exclusive loving devotion to the Supreme Lord  are  situated  completely  in
sattva guna the mode of goodness.

The words aphala-akanksibhih means those who have  no  desire  for  rewards.
Those devout and evolved jivas or embodied beings  with  ardent  faith,  who
are imbued  with  the  consciousness  that  all  their  actions  are  humble
offerings of worship rendered to the Supreme Lord  Krishna  or  any  of  His
authorized incarnations and expansions  as  revealed  in  Vedic  scriptures;
performing the three aforementioned  types  of  austerity  of  the  physical
body, speech and mind are known to be in sattva guna the mode of goodness.
