Neti Neti

Why Neti Neti Brahman? Why no positive description?

The description of Brahman: “Not this, not this” (Neti, Neti); for there is no other and more appropriate description than this “Not this.” Now the designation of Brahman: “The Truth of truth.” — Brihadaranyaka Upanishad 2.3.6 —

“NOT THIS, NOT THIS”: Brahman does not possess any distinguishing marks which can be described by words. By the elimination of all differences due to limiting adjuncts, the words Not This, Not This refer to some thing which has no distinguishing mark such as name, or form, or action, or heterogeneity, or species, or qualities. These two negative particles are used in an all-inclusive sense, so as to eliminate every possible specification that may occur.”
