The book brought to the attention of the reader by Vladimir Shmakov is a brilliant result of the further development and deepening of those ideas and principles that were developed by him in his previously published work “The Sacred Book of Thoth. The Great Arcana of the Tarot."

"Fundamentals of Pneumatology", being a solid and logically completed book, at the same time form part of his "System of Esoteric Philosophy".

This book is of particular interest precisely in our difficult time is a time of understanding our place in the world and relationships with it and is designed for a much wider range of intellectual readers than “Arcana Tarot”. Its only publication was made in Moscow in 1922. It was not possible to find the original for the reprint edition.

At the same time, another book by Vl. Shmakov from the “System of Esoteric Philosophy” “The Law of Synarchy and the Doctrine of the Duality of the Hierarchy of Monads and Sets.”
