हिंदी अनुवाद - स्वामी रामसुख दास जी ( भगवद् गीता 7.2)
।।7.2।।तेरे लिये मैं विज्ञानसहित ज्ञान सम्पूर्णतासे कहूँगा जिसको जाननेके बाद फिर यहाँ कुछ भी जानना बाकी नहीं रहेगा।


Rudra Vaishnava Sampradaya - Commentary





Lord Krishna praises the  transcendental  knowledge  that  He  is  about  to
instruct as it leads to blessedness  and  realisation.  This  transcendental
knowledge  is  the  essence  of  Vedanta  and  derivable  from   the   Vedic
scriptures. Its realisation guarantees that there is nothing further  to  be
known by one who is an  aspirant  for  moksa  or  liberation  from  material
existence. Such a person becomes exalted by such realisation alone.


Brahma Vaishnava Sampradaya - Commentary





The word jnana means Vedic  knowledge  but  the  compound  word  sa-vijnanam
indicates transcendental spiritual awareness concerning  the  Supreme  Lord.
Lord Krishna is stating that He will reveal the complete process  and  means
for achieving it


Shri Vaishnava Sampradaya - Commentary





Lord Krishna  has  deigned  to  reveal  completely  in  detail  the  general
knowledge concerning Him as well as the  esoteric  knowledge  which  can  be
realised. The word vijnana means realised knowledge.  This  denotes  a  more
profound level of understanding with a special propensity  of  inate  wisdom
which can discern and discriminate the reality of the Supreme  Lord  Krishna
being the original substratum and foundation of  all  that  is  animate  and
inanimate in existence. He is the ultimate  controller,  the  antithesis  to
whatever is demoniac. He is the sovereign master of all creation  possessing
unlimited  divine  glories  and  infinite   transcendental   qualities   and
attributes. Along with revealing these things Lord Krishna will also  reveal
the wisdom concerning His manifested nature.  By  the  realisation  of  this
spiritual knowledge there will be nothing left  worthy  of  knowing  for  an
aspirant of bhakti or unconditional loving devotion. The extreme  difficulty
in acquiring  such  esoteric  knowledge  about  the  Supreme  Lord  will  be
explained in the following verse.
