“Now, I am become Death, the destroyer of worlds.”
J. Robert Oppenheimer quoting the Bhagavad Gita as he watched his creation, the first atomic bomb, successfully detonate.
Actual quote from the Bhagavad Gita:
sri-bhagavan uvaca:
kalo ‘smi loka-ksaya-krt pravrddho
lokan samahartum iha pravrttah /
rte ‘pi tvam na bhavisyanti sarve
ye ‘vasthitah pratyanikesu yodhah //
The Lord said: “Time [death] I am, the destroyer of the worlds, who has come to annihilate everyone. Even without your taking part all those arrayed in the [two] opposing ranks will be slain!”
(Gita vs. 11.32
