Thought and character are one, and as character can only manifest and discover itself through environment and circumstance, the outer conditions of a person’s life will always be found to be harmoniously related to his inner state. This does not mean that a man’s circumstances at any given time are an indication of his entire character, but that those circumstances are so intimately connected with some vital thought-element within himself that, for the time being, they are indispensable to his development.
Every man is where he is by the law of his being; the thoughts which he has built into his character have brought him there, and in the arrangement of his life there is no element of chance, but all is the result of a law which cannot err. This is just as true of those who feel “out of harmony” with their surroundings as of those who are contented with them.
~ James Allen – As A Man Thinketh (1903)
