In plain words
So look, and look closely — with reasoning, and with what the śruti says: at what is the same all through, always shining, free of the duality your own mind frames as 'it is' and 'it is not'. Whoever has the discernment to see this reaches nirvāṇa with nothing left over, the way a lamp goes out.
Close to the Sanskrit
Therefore, having closely examined — by reasoning and from scripture — that which is the same, constantly shining, free from the duality imagined as existent and non-existent, the intelligent one reaches nirvāṇa without remainder, like a lamp.
