God hissed, and there was light

“God hissed, and there was light” is Belbo’s comic, compressed formulation of the creation story that Diotallevi attributes to Isaac Luria. The phrase makes the birth of light audible, joining the act of creation to the breath that produces it and to the catastrophe of vessels unable to contain the divine outpouring.

The Lurianic account

Diotallevi describes Luria’s account as a departure from the orderly articulation of the Sefirot: creation proceeds through divine inhalation and exhalation, like anxious breathing or bellows in motion. Belbo first glosses this image as “God’s asthma,” making cosmic creation sound bodily and almost involuntary. The conversation then recasts the divine act as blowing a glass bubble: God takes a deep breath, holds it, and releases a long, luminous hiss identified with the ten Sefirot.

Sound, light, and rupture

The phrase “God hissed, and there was light” answers the question of whether a hiss of light is possible by collapsing sound and illumination into a single act. Its playful bluntness gives the abstract emanation a physical voice, while its echo of the biblical creation formula lends that joke a cosmogonic scale. The surrounding account also makes the hiss consequential: the vessels receiving Keter, Hokhmah, and Binah withstand the splendor, but the lower vessels, from Hesed to Yesod, break when light is exhaled too strongly in one burst. Fragments spill into the universe, and gross matter is born from that breakage.

Function in the conversation

The line condenses the passage’s movement from metaphysical explanation to conversational wit. Belbo’s gloss does not undo Diotallevi’s account; it gives its breathing imagery a memorable comic form, which the next remark, “Multimedia,” extends by treating creation as a fusion of media. Beneath the joke, the phrase preserves the account’s tension: the same breath that brings light into being also overwhelms the vessels meant to contain it, making creation inseparable from rupture.
