The teaching in one sentence
Wishing for freedom from defilements accomplishes nothing on its own; what actually produces that freedom is development of a specific, named set of qualities, and a mendicant who has genuinely developed them may reach that same freedom without even needing to wish for it.
The full thirty-seven, named as a set
What must be developed is given as seven categories in one breath: the four kinds of mindfulness meditation, the four right efforts, the four bases of psychic power, the five faculties, the five powers, the seven awakening factors, and the noble eightfold path — the complete thirty-seven qualities contributing to awakening (bodhipakkhiyā dhammā), here named together as a single group rather than treated individually.
A hen who wishes without sitting on her eggs
A hen with eight, ten, or twelve eggs who has not properly sat on them to keep them warm cannot make her chicks hatch safely no matter how much she might wish it — the wishing changes nothing, because what the chicks actually need is the incubation itself, not the hen's desire for the outcome.
The same simile, reversed
A hen who has properly incubated her eggs need not even wish for her chicks to hatch safely; they can do so regardless, because the actual condition — sustained incubation — has already been met. The discourse restates its entire opening claim this way, showing that development, once genuinely present, makes the wish itself beside the point.
Progress too gradual to notice, until it's done
Two further similes describe how this development actually unfolds: a carpenter's adze handle worn smooth by handling, with no way to say how much wore away today, yesterday, or before — only that it has worn away; and a ship's ropes, weathered by six months in water and then by wind, sun, and rain on dry land, that collapse and rot away not from any single dramatic event but from sustained, imperceptible exposure. A mendicant committed to development wears away their fetters the same gradual way.

The text
Without development, the wish is not enough
§1“Mendicants, when a mendicant is not committed to development, they might wish: ‘If only my mind were freed from the defilements by not grasping!’ Even so, their mind is not freed from defilements by not grasping. Why is that? You should say: ‘It’s because they’re undeveloped.’ Undeveloped in what? The four kinds of mindfulness meditation, the four right efforts, the four bases of psychic power, the five faculties, the five powers, the seven awakening factors, and the noble eightfold path. Suppose there was a chicken with eight or ten or twelve eggs. But she had not properly sat on them to keep them warm and incubated. Even if that chicken might wish: ‘If only my chicks could break out of the eggshell with their claws and beak and hatch safely!’ Still they can’t break out and hatch safely. Why is that? Because she has not properly sat on them to keep them warm and incubated. In the same way, when a mendicant is not committed to development, they might wish: ‘If only my mind were freed from the defilements by not grasping!’ Even so, their mind is not freed from defilements by not grasping. Why is that? You should say: ‘It’s because they’re undeveloped.’ Undeveloped in what? The four kinds of mindfulness meditation, the four right efforts, the four bases of psychic power, the five faculties, the five powers, the seven awakening factors, and the noble eightfold path.
With development, the wish is not even needed
§2When a mendicant is committed to development, they might not wish: ‘If only my mind were freed from the defilements by not grasping!’ Even so, their mind is freed from defilements by not grasping. Why is that? You should say: ‘It’s because they are developed.’ Developed in what? The four kinds of mindfulness meditation, the four right efforts, the four bases of psychic power, the five faculties, the five powers, the seven awakening factors, and the noble eightfold path. Suppose there was a chicken with eight or ten or twelve eggs. And she properly sat on them to keep them warm and incubated. Even if that chicken doesn’t wish: ‘If only my chicks could break out of the eggshell with their claws and beak and hatch safely!’ Still they can break out and hatch safely. Why is that? Because she properly sat on them to keep them warm and incubated. In the same way, when a mendicant is committed to development, they might not wish: ‘If only my mind were freed from the defilements by not grasping!’ Even so, their mind is freed from defilements by not grasping. Why is that? You should say: ‘It’s because they are developed.’ Developed in what? The four kinds of mindfulness meditation, the four right efforts, the four bases of psychic power, the five faculties, the five powers, the seven awakening factors, and the noble eightfold path.
The carpenter's adze handle, and the ship's ropes
§3Suppose a carpenter or their apprentice sees the marks of his fingers and thumb on the handle of his adze. They don’t know how much of the handle was worn away today, how much yesterday, and how much previously. They just know what has been worn away. In the same way, when a mendicant is committed to development, they don’t know how much of the defilements were worn away today, how much yesterday, and how much previously. They just know what has been worn away. Suppose there was a sea-faring ship bound together with ropes. For six months they deteriorated in the water. Then in the cold season it was hauled up on dry land, where the ropes were weathered by wind and sun. When the clouds soaked it with rain, the ropes would readily collapse and rot away. In the same way, when a mendicant is committed to development their fetters readily collapse and rot away.”
