। ॥ १४१ ॥
In plain words
The Self blazes with a light that is undivided, eternal, non-dual, boundless in its splendor -- and yet this power of concealment, thick with darkness, wraps itself around that light, hiding it, the way Rahu swallows the sun's disc in an eclipse.
Close to the Sanskrit
This power of concealment, made of darkness, covers the Self -- who is shining with the undivided, eternal, non-dual power of consciousness, of infinite majesty -- just as Rahu covers the orb of the sun during an eclipse.
