The Sage is often loosely described as ‘one that knows
the Self’. But this is not intended to be taken in a literal sense.
It is a tentative description, intended for those that believe
ignorance to be something that exists; they are told that this
ignorance is to be got rid of by winning ‘Knowledge of the
Self’. There are two misconceptions in this. One is that the
Self is an object of knowledge. The other is that the Self is
unknown, and needs to be known. The Self being the sole
Reality, He cannot become an object of knowledge. Also being
the Self, He is never unknown. The ancient lore tells us that
He is neither known nor unknown, and the Sage confirms it.
