ज्ञातृज्ञानज्ञेयभेदः परे नात्मनि विद्यते ।चिदानन्दैकरूपत्वाद्दीप्यते स्वयमेव तत् ॥ ४१ ॥
In plain words
In the supreme Self there is no split into a knower, an act of knowing, and a thing known. Its nature is a single thing — awareness that is bliss — and so it shines entirely by itself.
Close to the Sanskrit
The division into knower, knowing, and known is not found in the supreme Self. Because its nature is one — consciousness and bliss — That shines by itself alone.
