There is one more piece to complete this: Theosophy (Blavatskian)
https://en.wikipedia.org/wiki/Theosophy_(Blavatskian)
"Theosophy is an esoteric religious movement established in the United States during the late nineteenth century. It was founded largely by the Russian émigrée Helena Blavatsky and draws its beliefs predominantly from Blavatsky's writings. Categorised by scholars of religion as part of the occultist current of Western esotericism, it draws upon both older European philosophies like Neoplatonism and Asian religions like Hinduism and Buddhism.
As taught by Blavatsky, Theosophy holds that there is an ancient and secretive brotherhood of spiritual adepts known as Mahatmas, who—although found across the world—are centered in Tibet. These Masters are believed to have cultivated great wisdom and seemingly-supernatural powers, and Theosophists believe that it was they who initiated the modern Theosophical movement through disseminating their teachings via Blavatsky. They believe that these Masters are attempting to revive knowledge of an ancient religion once found across the world and which will again come to eclipse the existing world religions. Theosophical groups nevertheless do not refer to their system as a "religion". Theosophy preaches the existence of a single, divine Absolute. It promotes an emanationist cosmology in which the universe is perceived as outward reflections from this Absolute. Theosophy teaches that the purpose of human life is spiritual emancipation and claims that the human soul undergoes reincarnation upon bodily death according to a process of karma. It promotes values of universal brotherhood and social improvement, although it does not stipulate particular ethical codes.
Theosophy was established in New York City in 1875 with the founding of the Theosophical Society by Blavatsky, Henry Olcott, and William Quan Judge. Blavatsky and Olcott relocated to India, where they established the Society's headquarters at Adyar, Tamil Nadu. Blavatsky described her ideas in two books, Isis Unveiled and The Secret Doctrine. Blavatsky was repeatedly accused of fraudulently producing purportedly supernatural phenomena, often in connection with these "masters.". Following Blavatsky's death in 1891, there was a schism in the Society, with Judge leading the Theosophical Society in America to secede. Under Judge's successor Katherine Tingley, a Theosophical community named Lomaland was established in San Diego. The Adyar-based Society was later taken over by Annie Besant, under whom it grew to its largest extent during the late 1920s, before going into decline.
Theosophy played a significant role in bringing knowledge of South Asian religions to Western countries, as well as in encouraging cultural pride in various South Asian nations. A variety of prominent artists and writers have also been influenced by Theosophical teachings. Theosophy has an international following, and during the twentieth century had tens of thousands of adherents. Theosophical ideas have also exerted an influence on a wide range of other esoteric movements and philosophies, among them Anthroposophy, the Church Universal and Triumphant, and the New Age. "
"Central to Theosophical belief is the idea that a group of spiritual adepts known as the Masters not only exist but were responsible for the production of early Theosophical texts.[38] For most Theosophists, these Masters are deemed to be the real founders of the modern Theosophical movement.[39] In Theosophical literature, these Masters are also referred to as the Mahatmas, Adepts, Masters of Wisdom, Masters of Compassion, and Elder Brothers.[39] They are perceived to be a fraternity of human men who are highly evolved, both in terms of having an advanced moral development and intellectual attainment.[39] They are claimed to have achieved extra-long life spans,[39] and to have gained supernatural powers, including clairvoyance and the ability to instantly project their soul out of their body to any other location.[40] These are powers that they have allegedly attained through many years of training.[40] According to Blavatsky, by the late 19th century their chief residence was in the Himalayan kingdom of Tibet.[39] She also claimed that these Masters were the source of many of her published writings.[39] "
