In plain words
Established in peace and the other qualities of readiness, the wise enquire steadily within themselves. Recognizing That, they leave behind the distress of becoming and shine fulfilled, abiding as the Reality of awareness and bliss. Is that deeply known Reality not you yourself?
Word for word
Having attained peace and the other qualifications, continually enquiring by themselves within themselves, the wise recognize That. Having left behind the great distress of becoming, they shine, all accomplished, ever abiding as that Reality of awareness and bliss. Are you yourself not that Reality, the true principle known through deep inward enquiry?
