Kena Upanishad 1:4-5 (That, Absolute, You)

Which by speech is not expressed but by which the voice is expressed,

That alone, the Absolute, you, know, and not this which they worship.

yad vaachaa nabhyuditam yena vaag abhyudyate

tad eva brahma tvam viddhi nedam yad idam upaasate.

Which by the mind is not understood but by which, they say, the mind is understood,

That alone, the Absolute, you, know, and not this which they worship.

yan manasaa na manute yenaahur mano matam

tad eva brahma tvam viddhi nedam yad idam upaasate

notes:

-         Some indicate these slokas are 4 & 5; some, 5 & 6 (with sloka 3 being 3 & 4)

-         Most translate the second lines of both of these slokas, which will be repeated again in the next three slokas, a most important mantra of sorts, along the lines of “know that alone to be Brahman,” but translated literally, the line would be: “That alone Brahman you know.” After much meditation on this, a flash of insight realized the three nouns of That, Brahman, and ‘you’ were being equated as one subject to the verb, know! thus: “That alone, the Absolute, you, know”
