। ॥ ५१८ ॥
In plain words
So, to cut ignorance clean through, let the clear-minded one go and win knowledge. Knowledge ripens by discriminating the Self from what is not the Self — and by nothing else.
Close to the Sanskrit
Therefore, for the cutting off of ignorance, the one of good intellect should bring about knowledge. Through discrimination between Self and non-Self knowledge is accomplished, not otherwise.
