"Humanity ardently seeks 'The Truth' and explores every avenue to it. In this process it has produced a special literature, which ranges the whole gamut of thought from the trivial to the sublime-up from Divination, through all the Philosophies, to the final lofty Truth of 'The Master Key'. The 'Master Key' is here given to the world as a means of tapping the great Cosmic Intelligence and attracting from it that which corresponds to the ambitions, and aspirations of each reader." So begins 'The Master Key System' by Charles H. Haanel. 'The Master Key System' is a classic work of self-empowerment.
