The doctrine that all phenomena and the ego have no reality, but are composed of a certain number of skandhas or elements, which disintegrate. The void, the sky, space. The universal, the absolute, complete abstraction without relativity. There are classifications into 2, 3, 4, 6, 7, 11, 13, 16, and 18 categories. The doctrine is that all things are compounds, or unstable organisms, possessing no self-essence, i.e. are dependent, or caused, come into existence only to perish. The underlying reality, the principle of eternal relativity, or non-infinity, i.e. śūnya, permeates all phenomena making possible their evolution. From this doctrine the Yogācārya school developed the idea of the permanent reality, which is Essence of Mind, the unknowable noumenon behind all phenomena, the entity void of ideas and phenomena, neither matter nor mind, but the root of both.
