Mary Morrissey
Morrissey used sentences from the Bible in her teaching, as well as the Talmud, the Tao Te Ching, Thoreau and others. Wishing to show the New Thought movement in a simple nature, Morrissey wrote the book New Thought: A Practical Spirituality. Published by Penguin in 2002, the book was made of short essays from 40 New Thought leaders. The book was used for academic work: in the book Alternative Psychotherapies Jean Mercer referred to it as a key book for understanding the "engagement with the spiritual world." In Jones & Bartlett's 2009 book, Spirituality, Health, and Healing, authors Young and Koopsen wrote that Morrissey's New Thought was important for understanding the difference between the New Thought movement and New Age, writing that "New Thought is not New Age". Many research books, including Oxford University Press' Gurus of Modern Yoga, write that Morrissey's New Thought book was an important book in helping to understand the New Thought group.
