The Master Key System, along with "The Science of Getting Rich" is the source of Rhonda Byrne's inspiration for the book and film "The Secret." Originally published in 1912 as a correspondence course, it teaches that everything around us was first developed as a thought. That means that thought, is the powerful catalyst towards turning any idea into a reality. Using thought as the manifestation of creative energy, The Master Key System will show you how to use the power of these thoughts to realize your dreams.
