A comprehensive, yet entertaining introduction to Advaita, the non-dual teaching which provides a completely reasonable explanation for who we are and the nature of the universe. There are many `self-help' approaches promising enlightenment and happiness but most are illogical and lack any proven capability. Advaita has a guru-disciple tradition stretching back for several thousand years and can guarantee the sincere seeker a progressive path to self-realization.A 21st Century treatment of this ancient eastern philosophy, this book addresses all of the issues that are covered by both traditional teachers from the lineage of Shankara, and by modem `satsang teaching' and Direct Path methods stemming from Ramana Maharshi and Krishna Menon. Topics are explained in an accessible and readable manner, using amusing quotations and stories along with an abundance of metaphors from a wide variety of sources. Some of the most difficult concepts are clarified, whilst recognizing that this knowledge is ultimately beyond language or intellectual understanding.The Book of One is perhaps the most accessible, articulate and relevant book on the nature of non-duality."An updated edition of Dennis' Advaitic treasure trove. It benefits from nine years further research into the traditional roots of Advaita-Vedanta. This new edition will become essential for students, seekers, scholars, and cultural historians."Greg Goode, author of `Standing as Awareness'"...a masterful and profoundly insightful survey of Advaita Vedanta Teaching and the Contemporary Scene"Alan Jacobs, President Ramana Maharshi Foundation UK"The Book of One' takes the reader step by step on an intellectual inquiry into the truth of oneself. It provides a critical examination of the meaning and purpose of one's life"Dr Kuntimaddi Sadananda, AchArya at Washington Chinmaya Mission
