For speech without insight would make known no name: “my mind was elsewhere”, he says, “I did not recognise this name”. Smell without insight would make known no odour: “my mind was elsewhere, I did not recognise this odour”. The eye without insight would make known no form: “my mind was elsewhere, I did not recognise this form”. The ear without insight would make known no sound: “I did not recognise this sound”. The tongue without insight would make known no taste of food: “I did not recognise this taste”. The hands without insight would make known no deed: “I did not recognise this deed”. The body without insight would make known neither pleasure nor pain: “I did not recognise this pleasure and pain”. The organ of generation without insight would make known neither bliss, nor delight, nor procreation: “I recognised neither this bliss, nor the delight, nor the procreation”. The feet without insight would make known no going: “I did not recognise this going”. And thought without insight would succeed in nothing, and the knowable would not be known.

Proof from the contrary, and it is taken from the most ordinary experience: from absent-mindedness.
A man listened but did not hear; looked but did not see; ate and did not notice the taste. And his excuse is always one: anyatra me manaḥ abhūt — “my mind was elsewhere”. The Upaniṣad repeats this phrase nine times running, and in the repetition lies the argument's whole force.
The conclusion is this: the organ was in place and in working order. The ear had not gone deaf, the eye had not gone blind, the tongue had not gone numb. Only the rider was missing — that very insight which in the previous mantra mounted them. And therefore nothing “was made known”.
The verb prajñapayet underlies the whole analysis: “to make known, to present”. The organ does not itself cognise; it only presents — and it can present only when there is someone to present to.
This sets right the habitual notion that the senses give us the world and reason then processes it. Here it is said otherwise: without insight the senses give nothing. Hearing without attention is not muffled hearing — it is none.
And the last line extends the same to thought itself: “thought without insight succeeds in nothing”. Even reflection, that is, is not the same as prajñā; one can think and not understand, as one can look and not see.
From here the direct step to the next mantra, where it will be said that one must seek not the object, but the one who takes it.
