Brahma Vaishnava Sampradaya - Commentary

What the yad viktri of the ksetra means what are its transformations and  by
what modifications is it affected. Yatas ca yat means  by  Him  the  Supreme
Lord the ksetra has  originated and that it is He alone  who  energized  it.
The words sa ca ya specifies the Supreme Lord also and indicates His form.

Now begins the summation.

The words yatas ca yat indicates that solely by the energy  of  the  Supreme
Lord all creation is energized. He is  the  sole  energizer.  Prerana  means
having similarity in thoughts. Sometimes  even  dialogue  is  called  samvad
similar talk. Since Lord Krishna energizes all creation  He  also  energizes
the thoughts of all and sometimes such thoughts manifest which  are  similar
to His own. This is natural. So He is known as anusarini  or  anusmanta  the
ordainer of thoughts which have divine origins in Him. The ksetrajna is  the
atma or eternal soul and is upadrishta or  the  witness  with  supra-natural
connecting abilities for thoughts and things divine which emanate  from  the
Supreme Lord and induces this in those  who  seek  self-realisation  of  the
atma and attainment of the ultimate consciousness. Lord Krishna infers  that
this can be known is by its effect.
