The first book in channeler Paul Selig's widely anticipated Mastery Trilogy leads you into an unprecedented journey of self-development, at once building your personal excellence and your ability to improve life for others. The channeled literature of Paul Selig -- who receives clairaudient dictation from unseen intellects called the Guides -- has quickly become the most important and celebrated expression of channeling since A Course In Miracles rose to prominence in the 1970s. Selig's three previous books -- I Am the Word, The Book of Love and Creation, and The Book of Knowing and Worth -- have won a growing following around the world for their depth, intimacy, and psychological insight. Now, Selig embarks upon an extraordinary new trilogy on the "Teachings of Mastery" with his inaugural volume: The Book of Mastery. The Book of Mastery provides a deeply practical prescription for heightening your abilities, aptitudes, and sense of personal excellence. The Guides' teachings go much further, however, instructing you how to improve life for others and, ultimately, for global humanity. As the Guides themselves put it: "We will tell you this: No one who reads these books will be left unchanged. They will be like molecular systems that reinvigorate and realign and reclaim the reader to themselves in their worth, in their identity and, beyond that, in their physical realm. Underline physical realm if you like. Because the physical realm that we teach in is about to go back to the stone ages unless you all get it together."
