।।15.14।।प्राणियोंके शरीरमें रहनेवाला मैं प्राणअपानसे युक्त वैश्वानर होकर चार प्रकारके अन्नको पचाता हूँ।


Rudra Vaishnava Sampradaya - Commentary




Continuing on Lord Krishna affirms that His potency  is  vaisvanara  or  the
digestive fire within the physical body  that  combing  with  the  prana  or
exhalation and the apana or inhalation digests the four types of food  eaten
by jivas or embodied beings which are chewed, sucked, licked or  drank.  The
first is that which is chewed by masticating the food into small  pieces  so
it can be swallowed such as bread and vegetables. Next is that which can  be
licked by the tongue and swallowed without chewing like honey  or  molasses.
After is that which can be  sucked  like  the  juice  within  sugarcane  and
finally is that which can be swallowed without chewing  such  as  soups  and
liquid beverages. Hence they are all different.


Brahma Vaishnava Sampradaya - Commentary


The Supreme Lord Krishna discloses that He is abiding in the  physical  body
as the fire of digestion known as vaisvanarah assisting  in  the  sustenance
of all jivas or embodied beings.


Shri Vaishnava Sampradaya - Commentary

Lord Krishna declares that He is vaisvanara the digestive fire  which  joins
together with the vital  breaths  of   prana  or  exhalation  and  apana  or
inhalation. Together they digest in the  stomach  the  four  kinds  of  food
which are foods that are khadva  or  chewed,  soshva  or  sucked,  lehya  or
licked and peya or drank.  In  these  last  three  verses  Lord  Krishna  is
specifying integral functions of the jivas or embodied  beings  and  of  the
Earth that are manifestations of His opulent glories. The  expressions  that
He becomes the light of  the  sun, moon and fire etc. are meant to  indicate
the predicated relationship that theses object have in regard to  Him.  That
fact  that  such  realtionships  exist  in  reference  to  all   things   is
substantiated in the next verse.
