Sanskrit
कालोऽस्मि लोकक्षयकृत्प्रवृद्धो लोकान्समाहर्तुमिह प्रवृत्तः । ऋतेऽपि त्वां न भविष्यन्ति सर्वे येऽवस्थिताः प्रत्यनीकेषु योधाः ॥
kālo'smi lokakṣayakṛt pravṛddho lokān samāhartum iha pravṛttaḥ ṛte'pi tvāṃ na bhaviṣyanti sarve ye'vasthitāḥ pratyanīkeṣu yodhāḥ
Translation
Time am I, laying desolate the world, Made manifest on earth to slay mankind! Not one of all these warriors ranged for strife Escapeth death; thou shalt alone survive.

Explanation
This is the line the chapter has been building toward since verse 25, where Arjuna’s own simile — teeth “like Time’s destroying flames” — already named, without being told, what he was looking at. Now Krishna confirms it directly, in the first person, with no simile left in the sentence: “kālo ‘smi,” I am Time. Everything that follows in this speech is a direct consequence of that identity claim rather than a separate teaching — because he is Time, the outcome of the war is not a future event Arjuna can still prevent or cause, it is already accomplished, and the fighting still to come is just the visible unfolding of a result that has, in the only sense that matters here, already happened.
