Yoga of Time Travel: How the Mind Can Defeat Time, by Fred Alan Wolf, from Theosophical Publishing/Quest Books, ISBN 083560828X. Time travel is not just science fiction; it is possible, says theoretical physicist Fred Alan Wolf. Citing an ancient Hindu meditative technique, "cheating time," he draws on yoga and quantum physics to show that time is a flexible projection of mind. Time travel could clarify our sense of self, purpose, the future and death, providing heroes a way to aid the entire community. We might not only visit the past but alter it, with a ripple effect on the present.
