- This article is about a plane of existence. In the context of Unicode, astral characters consist of planes above the Basic Multilingual Plane.
The astral plane, also called the astral world, is a plane of existence postulated by classical (particularly neo-Platonic), medieval, oriental and esoteric philosophies and mystery religions. It is the world of the planetary spheres, crossed by the soul in its astral body on the way to being born and after death, and generally said to be populated by angels, spirits or other immaterial beings. In the late 19th and early 20th century the term was popularised by Theosophy and neo-Rosicrucianism.

Plato and Aristotle taught that the stars were composed of a type of matter different from the four earthly elements - a fifth, ethereal element or quintessence. In the "astral mysticism" of the classical world the human psyche was composed of the same material, thus accounting for the influence of the stars upon human affairs. In his commentaries on Plato's Timaeus, Proclus wrote;
"Man is a little world (mikros cosmos). For, just like the Whole, he possesses both mind and reason, both a divine and a mortal body. He is also divided up according to the universe. It is for this reason, you know, that some are accustomed to say that his consciousness corresponds with the nature of the fixed stars, his reason in its contemplative aspect with Saturn and in its social aspect with Jupiter, (and) as to his irrational part, the passionate nature with Mars, the eloquent with Mercury, the appetitive with Venus, the sensitive with the Sun and the vegetative with the Moon."
Such doctrines were commonplace in mystery-schools and Hermetic & gnostic sects throughout the Roman Empire and influenced the early Christian church. Among Muslims the "astral" world-view was soon rendered orthodox by Quranic references to the Prophet's ascent through the seven heavens. Scholars took up the Greek Neoplatonist accounts as well as similar material in Hindu and Zoroastrian texts. The expositions of Ibn Sina (Avicenna), the Brotherhood of Purity and others, when translated into Latin in the Norman era, were to have a profound effect upon European mediaeval alchemy and astrology. By the 14th century Dante was describing his own imaginary journey through the astral spheres of Paradise.
Throughout the Renaissance, philosophers, Paracelsians, Rosicrucians and alchemists continued to discuss the nature of the astral world intermediate between earth and the divine. Once the telescope established that no religious heaven was visible around the solar system, the idea was superseded in mainstream science.
The astral plane and astral experience 
According to occult teachings the astral plane can be visited consciously through astral projection, meditation and mantra, near death experience, lucid dreaming, or other means. Individuals that are trained in the use of the astral vehicle can separate their consciousness in the astral vehicle from the physical body at will.
In early theosophical literature the term "astral" may refer to the aether. Later theosophical authors such as Annie Besant and C. W. Leadbeater make the astral finer than the etheric plane but "denser" than the mental plane. In order to create a unified view of seven bodies and remove earlier Sanskrit terms, an etheric plane was introduced and the term "astral body" was used to replace the former kamarupa - sometimes termed the body of emotion, illusion or desire.
According to Max Heindel's Rosicrucian writings, desire-stuff may be described as a type of force-matter, in incessant motion, responsive to the slightest feeling. The desire world is also said to be the abode of the dead for some time subsequent to death. It is also the home of the archangels. In the higher regions of the desire world thoughts take a definite form and color perceptible to all, all is light and there is but one long day.
In his book Autobiography of a Yogi, Paramhansa Yogananda provides details about the astral planes learned from his resurrected guru. Yogananda reveals that nearly all individuals enter the astral planes after death. There they work out the seeds of past karma through astral incarnations, or (if their karma requires) they return to earthly incarnations for further refinement. Once an individual has attained the meditative state of nirvikalpa samadhi in an earthy or astral incarnation, the soul may progress upward to the "illumined astral planet" of Hiranyaloka. After this transitionary stage, the soul may then move upward to the more subtle causal spheres where many more incarnations allow them to further refine before final unification.
Astral projection author Robert Bruce describes the astral as seven planes that take the form of planar surfaces when approached from a distance, separated by immense coloured "buffer zones". These planes are endlessly repeating ruled Cartesian grids, tiled with a single signature pattern that is different for each plane. Higher planes have bright, colourful patterns, whereas lower planes appear far duller. Every detail of these patterns acts as a consistent portal to a different kingdom inside the plane, which itself comprises many separate realms. Bruce notes that the astral may also be entered by means of long tubes that bear visual similarity to these planes, and conjectures that the grids and tubes are in fact the same structures approached from a different perceptual angle.
