"As a Man Thinketh" presents the power of thought, and particularly the use and application of thought to achieve happiness, personal goals and defeat our deepest issues. The book is simple, so that all can easily grasp and follow its teaching, and put into practice the methods which it advises. It shows how, in its own thought-world, every person holds the key to every condition, good or bad, that enters into their life, and that, by working patiently and intelligently upon their thoughts, they can remake their life, and transform their circumstances. This edition also includes the sequel to this famous book, "Out from the Heart."

James Allen was a British philosophical writer known for his inspirational books and poetry and as a pioneer of the self-help movement.
