A structural image, not a causal chain
The four-part bodily simile — hands, feet, joints, belly — each names an anatomical part whose mere presence or absence determines whether a certain kind of activity or experience is even possible, not one that actively causes it moment to moment. The discourse transfers this same possibility-condition logic to the sense faculties themselves.
Two mirrored halves, presence and absence
The discourse states its case twice: first for the presence of hands, feet, joints, belly, and the six senses (each “is found”), then for their absence (each “isn't found”) — the identical two-directional shape this vagga's own SN 35.230 and SN 35.231 have already used for other claims.
Pleasure and pain, not merely contact
Where many discourses in this book stop at naming contact itself as what depends on the sense faculty's presence, this discourse specifically names “pleasure and pain arising internally, conditioned by contact” — ajjhattaṁ sukhaṁ dukkhaṁ — as what the faculty's presence makes structurally possible.
A twin discourse to follow
This is the first of a paired “twin” discourse, a pattern this project has met often throughout this book: SN 35.237 immediately following restates the identical content with a single grammatical substitution, closing both this discourse's own pair and Samuddavagga itself.

The text
§1“Mendicants, when there are hands, picking up and putting down are found. When there are feet, coming and going are found. When there are joints, contracting and extending are found. When there’s a belly, hunger and thirst are found. In the same way, when there’s an eye, pleasure and pain arise internally conditioned by eye contact. When there’s an ear … nose … tongue … body … mind, pleasure and pain arise internally conditioned by mind contact.
§2When there are no hands, picking up and putting down aren’t found. When there are no feet, coming and going aren’t found. When there are no joints, contracting and extending aren’t found. When there’s no belly, hunger and thirst aren’t found. In the same way, when there’s no eye, pleasure and pain don’t arise internally conditioned by eye contact. When there’s no ear … nose … tongue … body … mind, pleasure and pain don’t arise internally conditioned by mind contact.”
