A who's who of the New Age movement, and guests, prescribes a what's what for global change--and despite the brevity of these short essays by 52 celebrities with a conscience, there's much to chew on. Not in Richard Gere's vague foreword, though (""If the cycles of conditioned violence and counter-violence can be avoided...we may re-enter the Garden of Peace and Bliss""); not in Yoko Ono's self-serving poem (""Remember you are loved. Remember I love you""); and not, let's hope, in the rather eccentric advice of physicist Helen Caldicott, who asks that we carry our groceries home by placing them--eggs, flour, what have you--into our own bottles and jars at the checkout counter, leaving the manufacturers' packaging behind. More moving and sound--sometimes extraordinarily sound--advice comes from more formidable figures--the Dalai Lama, Vaclav Havel, Rupert Sheldrake, Allen Ginsberg, Thich Nhat Hanh, Father Thomas Keating, Prince Philip (calling for ""a new vision in business""); and then there're Paul and Linda McCartney, who come up with a neat guideline for aspiring vegetarians: ""If it has a face, don't eat it!""
