The current state of confusion about the real nature of spiritual experience is due to a lack of understanding of how the brain functions as a channel for the expression of consciousness. In this book, Gopi Krishna challenges scientists and psychiatrists alike to stop ignoring the important part the physical brain plays in our development. He asserts that an understanding of prana, the super-intelligent cosmic energy behind all forms of life, is the key to understanding how higher forms of reality and other planes of creation, currently inaccessible to us, will become available for exploration.
