This book is about our lost sense. It is the sense that is the key to our being fully, vitally alive. We have been maimed by a variety of influences; we are handicapped in the same way that a blind or deaf person is limited. We have not fully used our potentials. More fundamental than sight or hearing or touch or smell or taste is our lost sense, the sense of our own being. This lost sense is the inward vision that makes it possible for us to be continually aware of how well our outer experience matches our inner nature. This is the existential sense.1
