The teaching in one sentence
The Realized One directly knows all the planes of consciousness, including the one who has settled into the formless dimension of nothingness as their final goal — and understanding that even the desire for rebirth in that dimension is a fetter is itself the brahmin’s knowledge of truth.
A rare kind of description
Posāla’s question describes someone at an unusually advanced meditative stage: “one who perceives that form has vanished, who has entirely given up the body, and who sees nothing at all internally and externally.” This is a description of the meditative attainment known as the “dimension of nothingness” (ākiñcaññāyatana), the third of the four formless absorptions, reached only after form and even the more subtle formless perceptions of infinite space and infinite consciousness have already been left behind. Posāla asks the Buddha, addressed as “the one who reveals the past,” how the knowledge of someone at this stage “should be guided” — what comes next for someone who has already gone this far.
All planes of consciousness
The Buddha’s answer opens by asserting a scope beyond even this attainment: the Realized One “directly knows all planes of consciousness” (viññāṇaṭṭhiti), a technical term elsewhere enumerated across seven stations plus two further exceptional cases. This isn’t simply confirming that the meditator’s attainment is real; it situates that attainment within a wider map the Buddha already sees completely, including “this one who remains, committed to that as their final goal” — a subtle but important phrase, since “committed to that as their final goal” already signals a problem before the answer states it directly.
Even nothingness is a fetter
The discourse’s sharpest turn comes next: “understanding that desire for rebirth in the dimension of nothingness is a fetter” is itself part of the required knowledge. This is a striking claim within the wider context of early Buddhist meditation instruction, where the formless attainments are often presented simply as increasingly refined states to be developed. Here, refinement is not enough on its own — even the subtlest possible object of craving, the experience of nothingness itself, remains an object of craving if held onto as a destination rather than passed through.
“Discerns that matter clearly”
The closing lines describe the further step: “directly knowing what this really means, one then discerns that matter clearly. That is their knowledge of truth, the brahmin who has lived the [holy] life.” The phrase “discerns that matter clearly” is compact enough to read past quickly, but its placement is deliberate: seeing through the fetter of craving even the dimension of nothingness is what allows genuinely clear discernment, rather than simply resting in an exceptionally quiet and refined absorption.
