The difference between “Meditations on the Tarot” and well-known works on Hermeticism and occult sciences is primarily in the fundamental novelty of execution: this is a classic of modern esoteric thought. The author's attempt to rethink the very foundations of Hermeticism - the Great Arcana of the Tarot - in the context of modernity was crowned with stunning success. The extraordinary nature of these “letters to an unknown friend” - i.e. like-minded reader - which shows the deep connection of the esoteric knowledge embodied in the Bible, Upanishads and Kabbalah, in that their author used “esoteric Christianity” as a reference point, namely, in his understanding, the teaching of the Church as a predetermined result and the key to understanding the entire path of humanity, towards solving the totality of its problems and the tasks facing it.
