As a Man Thinketh is James Allen's third book. He described it as "A book that will help you to help yourself", "A pocket companion for thoughtful people", and "A book on the power and right application of thought." It was first published in 1903—most sites incorrectly claim that the book was published in 1902. The first edition was published by The Savoy Publishing Company and was pocket size and daintily bound in cream leatherette with gold lettering.
Man is the creator and shaper of his destiny by the thoughts which he thinks. He rises and falls in exact accordance with the character of the thoughts which he entertains. His environment is the result of what he has thought and done in the past, and his circumstances in the future are being shaped and built by his present desires, aspirations, thoughts and actions. He therefore who chooses and pursues a particular line of thought, consciously builds his own destiny. This the book makes this clear.
It is beautifully written, practical, and breathes throughout a tone of high spirituality. It is full of the highest teaching, and will be a source of inspiration to everyone who ponders its words of truth. It is written with a forcible and lucid style, and the subjects are presented in such a manner that the reader cannot fail to be interested and helped. It contains a great deal of wisdom, tersely and beautifully expressed. Every page breathes the spirit of a calm, thoughtful, and religious mind. The tone is like that of a grateful melody that at once soothes and inspires. It is always true, and touches the soul but to bless it.
