In metaphysics and esoteric cosmology, a plane of existence (sometimes called simply a plane, dimension, vibrating plane, or an inner, invisible, spiritual, supraphysical world or egg) is a theoretical region of space and/or consciousness beyond the known physical universe, or the region containing the universe itself. Many esoteric teachings (e.g., theosophy and rosicrucianism) propound the idea of a whole series of subtle planes or worlds or dimensions which, from a center, interpenetrate themselves and the physical planet in which we live, the solar systems, and all the physical structures of the universe. This interpenetration of planes culminates in the universe itself as a physical structured, dynamic and evolutive expression emanated - through a series of stages, becoming progressively more material and embodied - from The Supreme Being: which allows from Itself the irruption of auto-Singularities, as the Big Bang, originated from Its unintelligible Chaos.
