‘Now I am become Death, the destroyer of worlds’. The story of Oppenheimer’s infamous quote

The Bhagavad-Gita is 700-verse Hindu scripture, written in Sanskrit, that centres on a dialogue between a great warrior prince called Arjuna and his charioteer Lord Krishna, an incarnation of Vishnu. Facing an opposing army containing his friends and relatives, Arjuna is torn. But Krishna teaches him about a higher philosophy that will enable him to carry out his duties as a warrior irrespective of his personal concerns. This is known as the dharma, or holy duty. It is one of the four key lessons of the Bhagavad-Gita: desire or lust; wealth; the desire for righteousness or dharma; and the final state of total liberation, or moksha.

Seeking his counsel, Arjuna asks Krishna to reveal his universal form. Krishna obliges, and in verse twelve of the Gita he manifests as a sublime, terrifying being of many mouths and eyes. It is this moment that entered Oppenheimer’s mind in July 1945. “If the radiance of a thousand suns were to burst at once into the sky, that would be like the splendour of the mighty one,” was Oppenheimer’s translation of that moment in the desert of New Mexico.

In Hinduism, which has a non-linear concept of time, the great god is not only involved in the creation, but also the dissolution. In verse thirty-two, Krishna speaks the line brought to global attention by Oppenheimer. “The quotation ‘Now I am become death, the destroyer of worlds’, is literally the world-destroying time,” explains Thompson, adding that Oppenheimer’s Sanskrit teacher chose to translate “world-destroying time” as “death”, a common interpretation. Its meaning is simple: irrespective of what Arjuna does, everything is in the hands of the divine.

“Arjuna is a soldier, he has a duty to fight. Krishna not Arjuna will determine who lives and who dies and Arjuna should neither mourn nor rejoice over what fate has in store, but should be sublimely unattached to such results,” says Thompson. “And ultimately the most important thing is he should be devoted to Krishna. His faith will save Arjuna’s soul.” But Oppenheimer, seemingly, was never able to achieve this peace. “In some sort of crude sense which no vulgarity, no humour, no overstatements can quite extinguish,” he said two years after the Trinity explosion, “the physicists have known sin; and this is a knowledge which they cannot lose.”
