Kumara Vaishnava Sampradaya - Commentary
In the very next reincarnation such a practicer of yoga or  the  science  of
the  individual  consciousness  attaining  communion   with   the   ultimate
consciousness is propelled by the impressions of the previous birth  and  is
drawn by the habits cultivated in their previous  existence.  Like  one  who
while performing  a  task  slumbers  briefly  but  when  roused  from  sleep
enthusiastically continues onwards to finishing  it.  In  the  same  way  in
their next birth such  a  practicer  of  yoga    enthusiastically  continues
onwards in perfecting yoga from where they left off in  the  previous  life.
Lord Krishna is declaring that the influence  of  yoga  and  the  past  life
habits involving yoga are so potent that they impel such a person  in  their
next life to gravitate towards yoga instinctively and intuitively as  if  it
were not in ones  power  to  resist.   Verily  the  majesty  and  greatness
of yoga is well known to be such.
