Meaning of the #Shlok
In this verse, Krishna is telling Arjuna who is grieving the probable deaths of everyone, that you and the ones you are grieving for, are all neither mind, brain nor body, but in fact souls. And because this soul is of the nature to remain unchangeable, therefore neither does it kill anyone nor does it itself die. Hence, this belief of yours that many people will die at your hands or that you yourself will die at someone’s hands is nothing but your misconception.
– Deep Trivedi
