In [[mathematics]], a '''plane''' is any flat, two-[[dimensional]] [[surface]]. A plane is the two dimensional analogue of a [http://en.wikipedia.org/wiki/Point_(geometry) point] (zero-dimensions), a [http://en.wikipedia.org/wiki/Line_(geometry) line] (one-dimension) and a [[space]] (three-dimensions). Planes can arise as subspaces of some higher dimensional space, as with the walls of a room, or they may enjoy an independent [[existence]] in their own right, as in the setting of [http://en.wikipedia.org/wiki/Euclidean_geometry Euclidean geometry].

When [[working]] in two-dimensional Euclidean space, the definite article is used, the plane, to refer to the whole [[space]]. Many [[fundamental]] tasks in [http://en.wikipedia.org/wiki/Geometry geometry], [http://en.wikipedia.org/wiki/Trigonometry trigonometry], and graphing are performed in two-dimensional space, or in other [[words]], in the plane. A lot of mathematics can be and has been performed in the plane, notably in the areas of geometry, trigonometry, graph theory and graphing.[http://en.wikipedia.org/wiki/Plane_%28geometry%29]

==Cosmology==

In [[esoteric]] cosmology, a plane, other than the [[physical]] plane is [[conceived]] as a subtle state of [[consciousness]] that [[transcends]] the known physical universe.

In [[esoteric]] cosmology, a plane, other than the [[physical]] plane is [[conceived]] as a subtle state of [[consciousness]] that [[transcends]] the known physical universe.

The concept may be found in [[religious]], and [[esoteric]] teachings - e.g. [http://en.wikipedia.org/wiki/Vedanta Vedanta] (Advaita Vedanta), [[shamanism]], [http://en.wikipedia.org/wiki/Hermeticism Hermeticism], Neoplatonism, [http://en.wikipedia.org/wiki/Gnosticism Gnosticism], Kashmir Shaivism, Sant Mat/Surat Shabd Yoga, Sufism, Druze, [http://en.wikipedia.org/wiki/Kabbalah Kabbalah], [http://en.wikipedia.org/wiki/Theosophy Theosophy], [http://en.wikipedia.org/wiki/Anthroposophy Anthroposophy], [http://en.wikipedia.org/wiki/Rosicrucianism Rosicrucianism] (Esoteric Christian), Eckankar, Ascended Master Teachings, etc. - which 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 system]]s, 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 steadily denser [[stages]], becoming progressively more [[material]] and embodied.

The [[emanation]] is conceived, according to [[esoteric]] teachings, to have been originated, at the [[dawn]] of the universe's [[manifestation]], in The [[Supreme Being]] Who sent out - from the unmanifested [[Absolute]] beyond [[comprehension]] - the [[dynamic]] force of creative [[energy]], as [[sound]]-[[vibration]] ("[[the Word]]"), into the abyss of [[space]]. On the other hand, it states that this [[dynamic]] [[force]] is being sent forth, through the ages, framing all things that constitute and inhabit the [[universe]].
