The following article is by one of the biggest names in the self help industry, James Allen, As a Man Thinketh.
The aphorism, “As a man thinketh in his heart so is he,” not only embraces the whole of a man’s being, but is so comprehensive as to reach out to every condition and circumstance of his life. A man is literally what he thinks, his character being the complete sum of all his thoughts.
As the plant springs from, and could not be without, the seed, so every act of man springs from the hidden seeds of thought, and could not have appeared without them. This applies equally to those acts called “spontaneous” and “unpremeditated” as to those which are deliberately executed.
Act is the blossom of thought, and joy and suffering are its fruit; thus does a man garner in the sweet and bitter fruitage of his own husbandry.
Man is a growth by law, and not a creation by artifice, and cause and effect are as absolute and undeviating in the hidden realm of thought as in the world of visible and material things. A noble and God-like character is not a thing of favor or chance, but is the natural result of continued effort in right thinking, the effect of long-cherished association with God-like thoughts. An ignoble and bestial character, by the same process, is the result of the continued harboring of groveling thoughts.
Man is made or unmade by himself. In the armory of thought he forges the weapons by which he destroys himself. He also fashions the tools with which he builds for himself heavenly mansions of joy and strength and peace. By the right choice and true application of thought, man ascends to the divine perfection. By the abuse and wrong application of thought he descends below the level of the beast. Between these two extremes are all the grades of character, and man is their maker and master.
Of all the beautiful truths pertaining to the soul which have been restored and brought to light in this age, none is more gladdening or fruitful of divine promise and confidence than this–that man is the master of thought, the molder of character, and the maker and shaper of condition, environment, and destiny.
As a being of power, intelligence, and love, and the lord of his own thoughts, man holds key to every situation, and contains within himself that transforming and regenerative agency by which he may make himself what he wills.
Man is always the master, even in his weakest and most abandoned state. But in his weakness and degradation he is a foolish master who misgoverns his “household.” When he begins to reflect upon his condition and search diligently for the law upon which his being is established, he then becomes the wise master, directing his energies with intelligence and fashioning his thoughts to fruitful issues. Such is the conscious master, and man can only thus become by discovering within himself the laws of thought. This discovery is totally a matter of application, self-analysis and experience.
Only by much searching and mining are gold and diamonds obtained, and man can find every truth connected with his being, if he will dig deep into the mine of his soul. That he is the maker of his character, the molder of his life, and the builder of his destiny, he may unerringly prove, if he will watch, control, and alter his thoughts, tracing their effects upon himself, upon others and upon his life and circumstances, linking cause and effect by patient practice and investigation. And utilizing his every experience, even the most trivial, everyday occurrence, as a means of obtaining that knowledge of himself which is understanding, wisdom, power. In this direction is the law of absolute that “He that seeketh findeth; and to him that knocketh it shall be opened.” For only by patience, practice, and ceaseless importunity can a man enter the door of the temple of knowledge.
