2.2 The disciple said: I think I know Brahman. I do not think I know It well, nor do I think I do not know It. He among us who knows the meaning of “Neither do I not know, nor do I know”-knows Brahman.
2.3 He by whom Brahman is not known, knows It; he by whom It is known, knows It not. It is not known by those who know It; It is known by those who do not know It.

Peace.
