"The Secret Doctrine" and "The Voice of the Silence," both of which are foundational texts of the Theosophical movement. "The Secret Doctrine" is a comprehensive study of cosmology, philosophy, and the ancient wisdom traditions of the East and West, while "The Voice of the Silence" is a spiritual guide that delves into the nature of the soul's journey and the path of self-realization.
However, "Studies in Occultism" is a real book, but it was not written by H. P. Blavatsky. It was compiled and edited by Alfred Percy Sinnett, who was a close associate of Blavatsky and an early Theosophist.
"Studies in Occultism" is a collection of letters and essays written by Blavatsky and other members of the Theosophical Society. The book was first published in 1881 and contains valuable insights into various occult and esoteric topics, including astral projection, spiritual development, and the nature of the unseen realms.
The work serves as a valuable resource for those interested in the early development of Theosophy and the exploration of occult principles. As with any esoteric literature, readers are encouraged to approach the content with an open mind, critical thinking, and an understanding of the historical context in which it was written.
