This extraordinary book is about the imagination - an underused and unappreciated human facility that can open up ways of engaging differently with the world and all forms of learning and wisdom, both ancient and modern. After reading it, and mulling over the ideas in it, I even began to have more meaningful dreams! The power of the writing is in its accessible and lucid language: clear and precise expositions of the most difficult and sophisticated concepts, which are also illustrated more imaginatively with poems. Essential reading for those who have a religious or spiritual sensibility but cannot devote themselves to a particular faith, this book is enlightening and inspirational.
