13.2-3 Somewhere in  the scriputures it is heard that 'The  Field-sensitizer must be worshipped'.  Is He the same as the Soul, or the Lord or an altogether different third entity ?  On a doubt regarding this problem -
 
The Bhagavat instructs-Idam etc.  Ksetrajnam etc.  For persons of wordly life their body  is the Ksetra  'Field'  where the seeds of action grow.  That is why their personal  Soul covered with incoming  (or foreign, not-natural)  dirt, is called Field-sensitizer. In the case of the enlightened persons, the self-same body is  [again]  the Ksetra,  But there is difference in etimological meaning viz :  It decays  the fetters of the result of action by means of consuming [it];  and it protects  [them] from the fear of birth-and-death  [cycle].  With reference to these  persons, the Supreme Soul, Vasudeva is the Field-sensitizer.  He who sensitizes this Field :  He who causes it to know.  Here the root vid includes within itself,  the meaning of the causal  suffix ni.  Therefore  [the meaning is :]  He, on account of Whose grace this insentient [body] attains the status of being sentient, He alone, an no one else, is the Field-sensitizer.  But, the  [only]  difference is this :  Taking into consideration th aspect of limited pervaisveness,  He is taken to be Soul; and on account of  [His] unlimited pervasiveness in all the Fields,  [He is called] the Supreme Soul, the Bhagavat  Vasudeva.  Of  Me :  the Sixth Case here is in the objective sense.  Hence the idea is :  I may be known by means  of  this knowledge.
