Acharya Prashant explains that if Arjun could see that in the highest sense, he is free of all identities and is the pure Self, there would be no question of grief. Grief exists only if one has accepted a mortal identity, an identity that involves taking birth, staying alive, and then expiring. Grief is not necessary or predestined; it has a clear and fundamental causal relationship with what you take yourself to be. Arjun is not grieving without reason; the reason is his identity. Shri Krishna attempts to instruct and educate Arjun in the highest identity possible, an identity free of all griefs, which is the identity of the pure Self, the Atman. You are the Atman itself; no identities apply to you. All births and deaths are in the domain of Prakriti (nature/matter), and you are not that. The most fundamental teaching of all wisdom literature is that any wisdom that does not bring you to a point of freedom from all material identities must be rejected. Freedom from all identities is the most fundamental wisdom, from which all other beautiful and useful truths and dictums can spring. Acharya Prashant further explains that the highest wisdom is to be able to see that you are beyond all molecular motion, as the witness of the entire material expanse. If that is too much to grasp, then at least see that all material is the same and never dies; it is immortal. All mortality belongs only to the ego (Ahankar). The body itself does not die; it is only the ego that dies. The body is wise enough not to weep because it knows it will only be oxidized. When the ego is put to rest, the body does not weep. Quoting Ramana Maharshi, the speaker says, "They say I am dying, but I am not going away. Where could I go? I am here." If you are the witness, you cannot go away. If you are the body, the body is also not going anywhere; what comes and goes is the illusion. The speaker also quotes Sage Ashtavakra, who says, "Either I am nothing at all, or I am everything at once." Individuality is a delusion and the cause of grief. We are not separate from anything. Once you see that, you become non-violent, because if you hurt another, you are hurting yourself, as you and the other are not distinct.
