सद्भाव एष भवतो मयोक्तो ज्ञानं यथा सत्यमसत्यमन्यत् ।
In plain words
This is what actually is, and I have laid it out for you: knowledge is what is real — everything else is not.
Close to the Sanskrit
This true nature of what is has been declared to you by me: how knowledge is real, [and] what is other than it, unreal.
