यो वेद वेदं स च वेद वेद्यं यो वेद वेद्यं न स वेद सत्यम् ॥ ४२ ॥
In plain words
Whoever knows the Veda knows the one thing there is to know. Whoever knows the knowable as a knowable does not know what is real.
Close to the Sanskrit
He who knows the Veda, he also knows the knowable; he who knows the knowable, he does not know the real.
