In plain words
Knowledge and ignorance: that pair belongs to the working world. It is the vocabulary of difference, a convenient way of speaking. Look at what is actually there and the distinction is simply not found. What is actually there is Brahman — and nothing other than this is.
Close to the Sanskrit
This is a condition of the empirical order — the conventional terminology of difference, namely 'knowledge' and 'ignorance'. From the standpoint of reality it does not exist at all; the reality is Brahman alone, and nothing other than this exists.
