Truth cannot be an object of knowledge. Only something impermanent can be an object of knowing. ~ Nisargadatta Maharaj
Without dimension or existence lies the transcendental substratum behind manifestation: the unmanifest, the mathematical equivalent to zero and infinity rolled into one. Just as zero is indispensable in mathematics, and infinity ever lurking, so too noumenon with respect to phenomena. Beyond ever-changing phenomena lies never changing noumenon.
There can be no knowledge of the unmanifested. Only the actual can be known. ~ Nisargadatta Maharaj
Noumenon cannot be described, as there is nothing to describe. All characterization is of phenomena, beginning with the localization of Ĉonsciousness to consciousness.
The manifestation of consciousness is itself duality. ~ Nisargadatta Maharaj
The mind deals in concepts. As concepts, phenomena and noumenon portray a duality. (Duality is inherent in conceptualization, which occurs via discrimination of generalities. Duality and diversity are tautological as the backbone of Nature.) The falsity of duality arises because all that can be conceived are concepts. The unicity of reality is beyond concepts.
Your true nature is beyond description. It cannot be known with the mind. It is the source of everything. ~ Nisargadatta Maharaj
Phenomena arise from noumenon via the abiding desire of Ĉonsciousness for entertainment. Nature is propelled by a will for animation which forms beauty by virtue of coherence.
Your mind projects a structure and you identify yourself with it. It is in the nature of desire to prompt the mind to create a world for its fulfillment. Even a small desire can start a long line of actions; what about a strong desire? Desire can produce a universe. Its powers are miraculous. Just as a small matchstick can set a huge forest on fire, so does a desire light the fires of manifestation. The very purpose of creation is the fulfillment of desire. ~ Nisargadatta Maharaj
