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 popularized by Theosophy and Neo-Rosicrucianism. Leadbeater's account is one of the most enduring. Charles Webster Leadbeater was an influential member of the Theosophical Society, an author on occult subjects and an associate of Annie Besant. Leadbeater went on to write over 69 books and pamphlets that examined in detail the hidden side of life as well as maintain regular speaking engagements. His efforts on behalf of the society assured his status as one of its leading members until his death in 1934.
