यो वेद वेदान्स च वेद वेद्यं न तं विदुर्वेदविदो न वेदाः ।

In plain words

Whoever really knows the Vedas knows also what they were pointing at. And him — the Veda-scholars do not know him, and the Vedas do not know him either.

Close to the Sanskrit

He who knows the Vedas, he also knows that which is to be known; him the knowers of the Vedas do not know, nor do the Vedas.
