(This entry is by Ralph Waldo Trine from his book THIS MYSTICAL LIFE OF OURS written in 1907, and is now in the public domain.)
Each individual life, after it has reached a certain age or degree of intelligence, lives in the midst of the surroundings or environments of its own creation; and this by reason of that wonderful power, the drawing power of mind, which is continually operating in every life, whether it is conscious of it or not.
We are all living, so to speak, in a vast ocean of thought. The very atmosphere about us is charged with the thought-forces that are being continually sent out. When the thought-forces leave the brain, they go out upon the atmosphere, the subtle conducting ether, much the same as sound-waves go out. It is by virtue of this law that thought transference is possible, and has become an established scientific fact, by virtue of which a person can so direct his thought-forces that a person at a distance, and in a receptive attitude, can get the thought much the same as sound, for example, is conducted through the agency of a connecting medium. Even though the thoughts as they leave a particular person, are not consciously directed, they go out; and all may be influenced by them in a greater or less degree, each one in proportion as he or she is more or less sensitively organized, or in proportion as he or she is negative, and so open to forces and influences from without. The law operating here is one with that great law of the universe, — that like attracts like, so that one continually attracts to himself forces and influences most akin to those of his own life. And his own life is determined by the thoughts and emotions he habitually entertains, for each is building his world from within. As within, so without; cause, effect.
A stalk of wheat and a stalk of corn are growing side by side, within an inch of each other. The soil is the same for both; but the wheat converts the food it takes from the soil into wheat, the likeness of itself, while the corn converts the food it takes from the same soil into corn, the likeness of itself. What that which each has taken from the soil is converted into is determined by the soul, the interior life, the interior forces of each. This same grain taken as food by two persons will be converted into the body of a criminal in the one case, and into the body of a saint in the other, each after its kind; and its kind is determined by the inner life of each. And what again determines the inner life of each? The thoughts and emotions that are habitually entertained and that inevitably, sooner or later, manifest themselves in outer material form.
Thought is the great builder in human life: it is the determining factor. Continually think thoughts that are good, and your life will show forth in goodness, and your body in health and beauty. Continually think evil and your life will show forth in evil, and your body in weakness and repulsiveness. Think thoughts of love, and you will love and will be loved. Think thoughts of hatred, and you will hate and will be hated. Each follows its kind.
