Sam Harris’ latest book Waking Up presents what the author describes as a “rational approach to spirituality.” Harris demonstrates that there is no separate, permanent, independent “self” at the core of one’s being. Self is an illusion but consciousness is very real. A human suffers when trying to align his or her consciousness with this illusory self, but the good news is this bondage can be broken by practicing mindfulness from one moment to the next. Breaking the illusion of self not only enables the clarity to enjoy things as they really are, but it also, says Harris, enables appreciation for the reality and nature of consciousness. Additionally, consciousness is also what gives life a moral dimension. Harris is very upfront about his experiences with mind-altering chemicals and draws upon not only his scientific knowledge but also his many years’ experience in meditative practices of various kinds. The book is a significant contribution to naturalistic spirituality.
