Why this discourse
This discourse opens Yakkhasaṃyutta with something distinct from a moral challenge or a personal struggle: a genuine philosophical puzzle, raised by the native spirit Indaka on his own home mountain. If the Buddhas teach that form isn't the soul, Indaka asks, how does ‘this one’ — a person — end up with a body at all? Where do bones and organs come from, and how does someone coalesce in the womb? Rather than a metaphysical deflection, the Buddha's answer is concretely developmental, tracing conception through named stages of growth to limb formation, hair, and nails, closing with the simple observation that the mother's own food and drink nourish the person growing within her.
Reading guide
A question asked on the questioner's own ground
Indaka doesn't seek the Buddha out elsewhere; the mountain itself, Indakūṭa, is named for him and described as his own haunt — the discourse taking place on the yakkha's home territory rather than the Buddha's own usual settings.
A puzzle built from the Buddha's own teaching
Indaka's question isn't hostile or skeptical of the teaching generally; it takes the specific claim that form isn't the soul as its starting premise, and asks a genuinely difficult follow-up: if that's true, how does embodiment happen at all?
An answer given in concrete, staged terms
Rather than a purely abstract or doctrinal response, the Buddha's reply moves through a specific developmental sequence — named stages of early growth, then limb buds, then hair and nails — treating the question as one that deserves a concrete, descriptive answer.
Ancient developmental terms, not modern embryology
The translation renders the four early stages using terms borrowed from modern embryology (zygote, blastocyst, gastrula, embryonic mass); this reading guide notes that the ancient Pali terms (kalala, abbuda, pesi, ghana) describe a traditional staged model of gestation, not a claim of precise correspondence with contemporary biological science.
Nourishment named as the final, grounding detail
The account doesn't end with anatomical formation alone; it closes on something plainly observable — whatever the mother eats and drinks nourishes the person growing within her — anchoring an otherwise technical account in ordinary experience.

pasākhā jāyanti, kesā lomā nakhāpi ca — “limb buds appear, the head hair, body hair, and nails” — the developmental sequence continuing past the earliest stages.
yañcassa bhuñjatī mātā, annaṁ pānañca bhojanaṁ — “whatever the mother eats…nourishes them there” — the account's closing, ordinary-life grounding detail.

The text
The discourse in full, opening Yakkhasaṃyutta. Translation: Bhikkhu Sujato (CC0, SuttaCentral).
§1So I have heard. At one time the Buddha was staying near Rājagaha on Mount Indra’s Peak, the haunt of the native spirit Indaka. Then the native spirit Indaka went up to the Buddha, and addressed him in verse:
§2“The Buddhas say that form is not the soul. Then how does this one obtain this body? From where do his bones and organs come? How does this one coalesce in the womb?”
§3“First there’s the zygote; then there’s the blastocyst; from there arises the gastrula; which produces the embryonic mass. From that the limb buds appear, the head hair, body hair, and nails.
§4And whatever the mother eats—the food and drink that she consumes—nourishes them there, the person in the mother’s womb.”
