James Allen (28 November 1864 – 24 January 1912) was a British philosophical writer known for his inspirational books and poetry and as a pioneer of the self-help movement. He never wrote theories, or for the sake of writing; but he wrote when he had a message, and it became a message only when he had lived it out in his own life, and knew that it was good. Thus he wrote facts, which he had proven by practice.
This book teaches us how to purify our hearts through the fundamental lessons of virtue: physical discipline, mental discipline, doing your best, self-honesty, and forgiveness. If assiduously practiced, these principles will lead to a blessed life of truth.
