The collection is dedicated to the study of occultism - the practice of exploring the subtle worlds and interacting with their beings and forces. The collection examines the theoretical and practical aspects of the occult discipline, explores the relationship between occultism and science, the relationship between Western and Eastern occultism, occultism and spirituality, describes the true principles and methods of occult practice, the basics of magic and protection against it, the principles of hypnotism, and provides specific cases from the occult practices. The collections of the series, compiled from fragments of the works of Sri Aurobindo and the Mother, examine practical issues of integral yoga, as well as everyday life from the perspective of integral yoga, because true spirituality is not the rejection of life, but the art of improving it. We hope that these publications will help you take a fresh look at yourself and your life and take another step towards self-development.
