A foundational work of early twentieth-century New Thought exploring the principles of thought, belief, and the shaping of human experience.
Originally issued under the title The Book of Life, this work presents Robert Collier's central ideas on the relationship between inner conviction and outward circumstance. Drawing on a wide range of philosophical, religious, and practical sources, Collier examines how thought directs action, how belief conditions outcome, and how disciplined attention may alter the course of one's life.
Written in a reflective and instructive register, the text moves between principle and illustration, offering a sustained argument for the formative power of the mind. Its emphasis is not on abstraction alone, but on application: the cultivation of habits of thought that align intention with result. In this respect, it stands alongside other early New Thought writings while retaining a distinct clarity of expression and purpose.
This edition restores the original title under which the work first appeared, situating it within its historical context while preserving the text in full for contemporary readers.
