About the book: year / It is human nature to acquire knowledge. Sailors roam the oceans, climbers climb mountain peaks, archaeologists penetrate underground in search of ancient artifacts, astronauts conquer the depths of space. But there is also a category of people who undertake to explore completely unknown territory - our internal spaces, located beyond the boundaries of familiar reality. This is amazing, educational and dangerous. This collection contains workshops that allow new testers to go through the described routes step by step, also dive into the depths of the subconscious and also try to expand the boundaries of their capabilities.
