This book combines knowledge of Buddhism, Christianity and modern science, but is not devoted to comparing their most interesting ideas, but to consistent contemplative penetration into the deep nature of reality. The first chapters consider the origin of meditation and scientific research on the benefits it brings. In the second part of the chapter they go in pairs - one is devoted to a certain practice of meditation, the other to the theory associated with it. The book's author, Dr. B. Alan Wallace, is a lecturer, scholar, and one of the most prominent Western authors and translators working in the field of Tibetan Buddhism. He tirelessly seeks innovative ways to combine the contemplative practices of Buddhism with Western science in order to contribute to the in-depth study of the mind.
