Other religions might structure their planes significantly differently. Physical plane The physical plane, physical world, or physical universe, in emanationist metaphysics taught in Neoplatonism, Hermeticism, Hinduism and Theosophy, refers to the visible reality of space and time, energy and matter: the physical universe in Occultism and esoteric cosmology is the lowest or densest of a series of planes of existence. According to Theosophists, after the material plane is the etheric plane and both of these planes are connected to make up the first (physical) plane. Theosophy also teaches that when the physical body dies the etheric body is left behind and the soul forms into an astral body on the astral plane. The psychical researcher F. W. H. Myers proposed the existence of a “metetherial world”, which he wrote to be a world of images lying beyond the physical world. He wrote that apparitions have a real existence in the metetherial world which he described as a dream-like world. Astral plane The astral plane, also called the astral world, is where consciousness goes after physical death. According to occult philosophy, all people possess an astral body. The astral plane (also known as the astral world) was postulated by classical (particularly neoplatonic), 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 non-physical beings. In the late 19th and early 20th century the term was popularised by Theosophy and neo-Rosicrucianism. Throughout the Renaissance, philosophers, Paracelsians, Rosicrucians and alchemists continued to discuss the nature of the astral world intermediate between Earth and the divine. The Barzakh, olam mithal or intermediate world in Islam and the "World of Yetzirah" in Lurianic Kabbalah are related concepts. 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. The Theosophist author Curuppumullage Jinarajadasa wrote: "When a person dies, they become fully conscious in the astral body. After a certain time, the astral body disintegrates, and the person then becomes conscious on the mental plane." Occultist George Arundale wrote: In the astral world exist
