Why this discourse

This discourse narrates a lunar eclipse as myth: the Moon God, seized by Rāhu, lord of titans, recollects the Buddha and calls on him for refuge. The Buddha commands Rāhu, in verse, to release the Moon, citing the Buddhas' compassion for the world. Rāhu complies at once, then rushes to Vepacitti, another titan lord, explaining that his head would have exploded in seven pieces had he not released the Moon when enchanted by the Buddha's verse. The discourse is still recited today as a protection chant (paritta).

Reading guide

A cosmological event narrated as a rescue

Ancient Indian cosmology explained lunar eclipses as the moon being swallowed by the titan Rāhu; this discourse takes that shared cosmology as its setting and narrates the eclipse's end as an act of rescue rather than an astronomical description.

Refuge invoked, not merely requested

The Moon God's verse follows the standard formula of taking refuge — homage to the Buddha, an appeal for shelter — used elsewhere in this collection for beings in danger, here applied to a deity caught in a titan's grip rather than a human seeking the Buddha's teaching.

The Buddha commands, does not merely ask

Unlike most exchanges in this book, where the Buddha answers a question or corrects a claim, here he issues a direct imperative to a third party, Rāhu, backed by an appeal to the Buddhas' compassion for the world rather than to Rāhu's own self-interest.

A head exploding in seven pieces

Rāhu's own account of his compliance is strikingly physical: not compassion or persuasion but the threat, understood by Rāhu himself, that his head would have exploded in seven pieces had he defied a verse spoken under the Buddha's influence — a folk-cosmological detail the text does not soften or explain away.

A myth still recited as protection

This discourse and its companion, SN 2.10 on the sun, remain in use today as protection chants (paritta), recited for shelter from harm — a continuity between this collection's ancient narrative and living devotional practice.

The text

The discourse in full: the Moon God's appeal, the Buddha's command to Rāhu, and Rāhu's own account to Vepacitti. Translation: Bhikkhu Sujato (CC0, SuttaCentral).

§1At Sāvatthī. Now at that time the Moon God had been seized by Rāhu, lord of titans. Then the Moon God, recollecting the Buddha, at that time spoke this verse:

§2“Homage to you, Buddha, hero! You’re free in every way. I’ve wandered into confinement: be my refuge!”

§3Then the Buddha addressed Rāhu in verse concerning the Moon God:

§4“The Moon God has gone for refuge to the Realized One, the perfected one. The Buddhas have compassion for the world—so Rāhu, release the Moon!”

§5Then Rāhu, having released the Moon, rushed to see Vepacitti, lord of titans and stood to one side, shocked and awestruck. Vepacitti addressed him in verse:

§6“Why the rush? Rāhu, you released the Moon and came here looking like you’re in shock: why do you stand there so scared?”

§7“My head would have exploded in seven pieces, I would have found no happiness in life, if, when enchanted by the Buddha’s verse, I had not released the Moon.”
