Abstract
The “All in Everything” conception has the oldest history among the models of integrity of Being that were developed in philosophy. It had already taken place in myth consciousness where it was expressed in principles of a “mystical participation”, syncretism and “whole instead of part”. This idea was developed in ancient Greek doctrines in connection with the problem of Onenes and Dozens. But the most fundamental role of the “All in Everything” principle is for ontologies of the Buddhism and the Advaita-Vedanta, that approves tripartite identity of all consciousness, the world of objects and the first principle of Being. In this article we consider the logic of coincidence at all levels of a universe, as it is presented in the doctrines of the Mahayana and the Advaita-Vedanta. The principle of universal coincidence of physical and mental objects is analyzed by means of the concept of modus, which is understood as a measurement, a side, a projection of primordial essence. The structure of the hologram is considered and analogies to the quantum theory of D. Bohm as a way of illustration “All in Everything” conception.
