Shri Vaishnava Sampradaya - Commentary

The word jnana means knowledge relative  to  the  atma  or  soul.  The  word
vijnana is transcendental knowledge based on realisation of the  atma.   The
word trptatma means one who is exclusively satisfied with  these  two  forms
of knowledge. The word kutastho refers to one who is perpetually  consistent
and unwavering amidst the variable and ever changing  phenomena of  material
existence. One who is  absorbed  in  the  eternal  nature  of  the  atma  is
kutastho and hence vijitendrah or one who has all the senses under  complete
subjugation. Such a person realising the atma and  perceiving  its  distinct
superiority to matter  is  never  again  infatuated  with  the  delusion  of
material pleasures  and  sense  gratification.  Thus  all  material  objects
whether they are gold or a clod of earth are of  equal  value  and  material
activities cease to give any pleasure seeking importance.  Such a person  is
known as yuktah meaning one in communion  with  the  ultimate  consciousness
and is a fit candidate to commence perfection of meditation which  leads  to
realisation of the Supreme Being. This is the purport of  the  Supreme  Lord
Krishna.
