In this work, Ken Wilber, known for his multifaceted approach and ability to present complex issues in the simplest possible way, offers an innovative perspective on the role of science, religion and spirituality in the modern world. Addressing a wide range of sources (from the spiritual traditions themselves to the latest discoveries in the natural and human sciences), using an integral approach, the author seeks to answer the questions of finding the place of spirituality in everyday life, evidence of the existence of the Spirit, stages of spiritual development, the role of meditation and contemplative practices, Eastern and Western approaches to religion.
