Wallace D. Wattles 
The Science of Getting Rich, Great And Well 

The purpose of the lessons in this book is to raise the mental and spiritual vibrations of the student – to inspire hope, faith, courage – to awaken larger thought within the mind, inspire greater plans and purposes and awaken the dormant energy in the life to fire the enthusiasm and call into active service hidden talent which the student, possibly, does not dream at his present stage of unfoldment, he possesses.

In short our purpose is to awaken men from mental slumber, show the unlimited resources in human nature, the unseen yet open doors to mental wealth first, then as a natural sequence to wealth in material conditions, and thus enlarge and ennoble the life as well as add to its material expressions.

This edition includes all three of Wattles‘ masterworks:

The Science of Getting Rich
The Science of Being Great
The Science of Being Well
