In Eight Pillars of Prosperity, James Allen expands on his beliefs that our thoughts and dreams determine the sort of person we will become. Here he reveals in great depth and detail the exact qualities we must meditate upon in order to achieve lasting success. He believed that prosperity rests on eight pillars: Energy, Economy, Integrity, System, Sympathy, Sincerity, Impartiality, and Self-reliance. "A business built up on the faultless practice of all these principles," Allen writes, "would be so firm and enduring as to be invincible. Nothing could injure it; nothing could undermine its prosperity, nothing could interrupt its success."

"The moral virtues are the foundation and support of prosperity as they are the soul of greatness. They endure forever, and all the works of man which endure are built upon them. Without them there is neither strength, stability, nor substantial reality, but only ephemeral dreams." - James Allen
