दृश्यते श्रूयते यद्यद्ब्रह्मणोऽन्यन्न तद्भवेत् ।तत्त्वज्ञानाच्च तद्ब्रह्म सच्चिदानन्दमद्वयम् ॥ ६४ ॥
In plain words
Whatever you see, whatever you hear — not one of these could be anything other than Brahman. And once reality is actually known, what stands is that Brahman: being, awareness, joy, one without a second.
Close to the Sanskrit
Whatever is seen, whatever is heard — that could not be other than Brahman; and from the knowledge of reality, that Brahman is being-consciousness-bliss, without a second.
