In plain words
The fourth is neither inward-knowing nor outward-knowing, nor knowing both ways; neither a mass of consciousness, nor ordinary knowing, nor unknowing. It is unseen, beyond transaction, ungraspable, without distinguishing mark, unthinkable, indescribable; its essence is the recognition of the one Self, the cessation of phenomenal projection, peace, auspiciousness, non-dual. That is the Self; that is to be known.
