This definition is an excellenet summary from Wikipedia, and I agree wtih 98% of it. The other 2% – I believe that sickness can start in the mind and/or the body; not just the mind, and that “God” is a religous manufactured term and description of what is actually Infinite Intelligence, and therefore should be removed from the definition….
“New Thought promotes the ideas that “Infinite Intelligence” or “God” is ubiquitous, spirit is the totality of real things, true human selfhood is divine, divine thought is a force for good, sickness originates in the mind, and “right thinking” has a healing effect.
Although New Thought is neither monolithic nor doctrinaire, in general modern day adherents of New Thought believe that “God” or “Infinite Intelligence” is “supreme, universal, and everlasting”, that divinity dwells within each person, that all people are spiritual beings, that “the highest spiritual principle [is] loving one another unconditionally … and teaching and healing one another”, and that “our mental states are carried forward into manifestation and become our experience in daily living”.
The New Thought movement is a spiritually-focused or philosophical interpretation of New Thought beliefs. Started in the early 19th century, today the movement consists of a loosely allied group of religious denominations, secular membership organizations, authors, philosophers, and individuals who share a set of beliefs concerning metaphysics, positive thinking, the law of attraction, healing, life force, creative visualization, and personal power. The three major religious denominations within the New Thought movement are Religious Science, Unity Church and the Church of Divine Science. There are many other smaller churches within the New Thought movement, as well as schools and umbrella organizations.”
