।।2.21।।हे पृथानन्दन जो मनुष्य इस शरीरीको अविनाशी नित्य जन्मरहित और अव्यय जानता है वह कैसे किसको मारे और कैसे किसको मरवाये


Rudra Vaishnava Sampradaya - Commentary

The denial of any possibility in the slaying of any living entity  has  been
established, for all living entities continually  maintain  their  existence
through the agency of the immortal soul.
Who can that person slay and how? When knowing its eternality which is  free
from modification, its immutability which is free from decay,  unborn  being
free from birth and   indestructible  being  free  from  death.  For  it  is
impossible to destroy the immortal soul  by  any  means.  So  who  then  can
factually claim to be the cause of another perishing? There is none who  can
claim this or  by any means achieve this. So the Supreme Lord by  clarifying
this point is also informing Arjuna  to that He  is  not  directing  him  to
slay anyone because the soul is factually never slain.


Brahma Vaishnava Sampradaya - Commentary

One who understands that the eternal soul is incapable  of  being  destroyed
who can be slain and how?  The word avinasinam means indestructible,  nityam
means eternal and therefore by its own inherent nature the immortal soul  is
imperishable without any defects because what  is  eternal  is  never  in  a
state of modification. The word defect is commonly used for  that  which  is
not of perfection. The physical body of the living entities is  not  perfect
it is defective, thus the word destruction is applicable   to  the  physical
body but never to the eternal soul.

Now begins the summation.

The word avinasinam is indicative  of  one  whose  body  is  indestructible.
Eternal in form only applies to the Supreme Lord. Unlimited activity is  the
attribute of being independent, total independence  is  found  only  in  the
case of the Supreme  Lord,  who  being  immutable  is  without  any  support
outside of Himself.


Shri Vaishnava Sampradaya - Commentary

So possessing  spiritual intelligence,  knowing  the  soul  to  be  eternal,
understanding it to be  birthless and deathless being  of  an  inexhaustible
nature how is it possible for  anyone  to  commit  any  act  of  destruction
against the immortal soul which dwells in trillions of various  and  diverse
living entities among the 8 million 400 thousand species of life  throughout
the billions of material universes. Whom can anyone destroy? How can  anyone
destroy anyone? Who can cause anyone to be destroyed? No one  can!  Thus  it
can be seen that ignorance of the eternal nature of the soul  is  the  cause
of all grief by not understanding that the soul  is  immortal  and  thinking
that  the  eternal  soul  perishes  when   the   physical   body   perishes.
Comprehending that what happens to the immortal soul when the physical  body
ceases to function is factually the withdrawal from an old physical body  to
enter into a new physical body. So it can be understood that those who  have
deep regret for the loss of the physical body, serving as  it  does  as  the
facility  for  securing  and  enjoying  material  pleasures;  these   living
entities should reflect on the futility  and  temporal  nature  of  material
existence rather than trying to eternally exploit their  senses.  This  will
be further expounded in the next verse.
