Theosophy - Cult Alert.

Theosophy (from Greek θεοσοφία theosophia, from θεός theos, God^[1] + σοφία sophia, wisdom; literally "God's wisdom"), refers to systems of esoteric philosophy concerning, or investigation seeking direct knowledge of, presumed mysteries of being and nature, particularly concerning the nature of divinity.

Theosophy is considered a part of the broader field of esotericism, referring to hidden knowledge or wisdom that offers the individual enlightenment and salvation. The theosophist seeks to understand the mysteries of the universe and the bonds that unite the universe, humanity, and the divine. The goal of theosophy is to explore the origin of divinity and humanity, and the world. From investigation of those topics, theosophists try to discover a coherent description of the purpose and origin of the universe. Wikipedia.

As far as I can best tell, Theosophy itself is a pretty rare bird in the twenty first century - it is more the longterm knock-on effects from this well-meaning, but definitely toxic creed, which beset us today. Its influences run deep. (What joins the snake head and its tail BTW?)
