संलक्ष्य चिन्मात्रतया सदात्मनो -रखण्डभावः परिचीयते बुधैः ।एवं महावाक्यशतेन कथ्यतेब्रह्मात्मनोरैक्यमखण्डभावः ॥ २५१ ॥
In plain words
See both as nothing but consciousness itself, and the wise recognize what was always true: Being and the Self were never two, only ever whole. This is what hundreds of great scriptural sentences keep saying, again and again: Brahman and the Self are one, undivided.
Close to the Sanskrit
Having discerned [both] as nothing but consciousness, the undivided nature of Sat [Being] and the Self is recognized by the wise. Thus, by hundreds of great sentences, the oneness of Brahman and the Self — the undivided state — is declared.
