Rudra Vaishnava Sampradaya - Commentary





Now Lord Krishna explains the path that leads to a return of rebirth in  the
material existence. When one accedes to death at the times presided  by  the
demigods identified with smoke, with night, with the waning  moon  and  with
the suns waning southern course guided on these paths  those  who  performed
ritualistic Vedic activities will reach  the  celestial  heavens  and  after
amply enjoying the fruits of their actions will return again and  be  reborn
in the world of mortals. The Brihadaranyaka Upanisad VI.II.XVI states:  They
first reach the demigod identified with smoke, etc. Thus  by  mediation  and
performing  selfless  Vedic  activities  without  desire  for  rewards   one
gradually achieves moksa or liberation from  material  existence  and  those
who perform Vedic activities with a desire for rewards and  benefits  return
to the material  worlds  after  enjoying  their  accumulated  merit  in  the
heavens. But those who go against the injunctions of  the  Vedic  scriptures
and do prohibited activities only return to material worlds after  prolonged
and agonising  suffering  in  the  lower  hellish  planets  when  all  their
demerits have been purged. While ordinary creatures of flora and  fauna  are
reborn again and again incessantly and continuously.

Shri Vaishnava Sampradaya - Commentary




The word dhumah meaning smoke indicates the presiding demigod of the path
in which lies the Pitri-loka the realm of the manes or ancestors. The word
yogi has been used to denote a spiritual person who performs Vedic
activities.
