“Kālo’smi loka-kṣaya-kṛt pravṛddhaḥ — I am Time, grown mighty, the destroyer of worlds; here I am engaged in withdrawing the worlds. Even without you, all these warriors arrayed in the opposing ranks shall cease to be.” This is the terrible centre of the whole Gītā. The speaker is no longer “the friend Kṛṣṇa” but Kāla — Time itself, the impersonal, all-consuming power under which every finite thing is already, in principle, undone. The clocks of these men have already run out; the vision merely shows Arjuna what is always true, and usually hidden. Death is not something Arjuna will do; it is something Time has already done, and Arjuna is only asked to let it appear through him.
