Arjuna's sight rested on bodies alone, and the way to bestow on him the sight of the “Ātma” is to separate body from Ātma: that separation is the goal of all sādhanas. Kṛṣṇa's teaching exists to teach this; this is its whole subject. Though Arjuna did not voice his doubts, Kṛṣṇa himself stated those doubts and gave the answer. “Arjuna! You grieve that you, and the royal kinsmen bound to you, will die because of you. You have recited dharmas, but the wise grieve neither for the dead nor for the living. Do you ask why they do not grieve? What you grieve for is bodies, is it not! Did you grieve over the states, the changes, the body passed through before? From infancy to childhood, from childhood to boyhood, from boyhood to youth, from youth to old age, and then the state of death. Death too is one of those states, is it not? How much did you grieve over those four states, that you should grieve over this state of death? Where is the body that played with your brothers when you were a child? It is not there, is it! The boy's body that bound Dhṛṣṭadyumna and brought him that day, is it here today? Yet you remember that event even now, do you not? In the same way, though your bodily states change, the Prajñāna that is the “Ātma” keeps for ever its immortal svarūpa. This is the mark of the jñānis.”
