Seth's effect upon New Age thinkers has been profound. The title jacket of "The Nature of Personal Reality, A Seth Book," published in 1994 (Amber-Allen/New World Library), contains testimonials from some of the most notable thinkers and writers within the movement. Marianne Williamson, Deepak Chopra, Shakti Gawain, Dan Millman, Louise Hay, Richard Bach, and others express the effect the Seth Material had upon their own awakening. In words similar to Williamson's they state: "Seth was one of my first metaphysical teachers. He remains a constant source of knowledge and inspiration in my life." Catherine L. Albanese, professor of religious history at the University of Chicago, stated that in the 1970s the Seth Material "launched an era of nationwide awareness" of the channeling trend. She believes it contributed to the "self-identity of an emergent New Age movement and also augment[ed] its ranks."  John P. Newport, in his study of the impact of New Age beliefs on contemporary culture, described the central focus of the Seth material as the idea that, for each individual: "you create your own reality." (Briefly summarized, our beliefs generate emotions which trigger our memories and organize our associations. Eventually those beliefs become manifested in our physical lives and health.) Newport wrote that this foundational concept of the New Age movement was first developed in the "Seth Material." Historian Robert C. Fuller, a professor of religious studies at Bradley University, wrote that Seth filled the role of guide for what Fuller called "unchurched American spirituality," related to concepts of reincarnation, karma, free will, ancient metaphysical wisdom, and "Christ consciousness."  Some writers noted, "Husband Robert Butts stated that similarities exist between Seth's ideas and those of various religious, philosophical, and mystical doctrines from the Near, Middle, or Far East... and we've done a little reading on Buddhism, Hinduism, Zen, and Taoism, for example, not to mention subjects like shamanism, voodooism, and obeah."  The late amateur physicist Michael Talbot wrote, "To my great surprise--and slight annoyance--I found that Seth eloquently and lucidly articulated a view of reality that I had arrived at only after great effort and an extensive study of both paranormal phenomena and quantum physics."
