As put forth in the film, The "Law of Attraction" principle posits that our feelings and thoughts affect real events in the world, from the workings of the entire cosmos, to interactions among individuals in their physical, emotional, and professional affairs. The film also suggests that there was a conspiracy to keep this central principle hidden from the public. The previews or "clues" to the film show Charles F. Haanel having "uncovered The Secret... Like the great men before him...", and his book, The Master Key System focuses heavily on this concept which is one of the book's key themes. On the DVD commentary section, Rhonda Byrne, creator, explains that she got inspired to create The Secret after reading the 1910 classic The Science of Getting Rich by Wallace D. Wattles.
