Crowd out all inferior thoughts by superior thoughts, evil thoughts by good thoughts, ugly thoughts by beautiful thoughts, distressing thoughts by pleasant thoughts, and you will begin to overcome the growth of all negative and confused states of wrong and discord. In other words, learn to think constructively of all persons, all things, all events, and all circumstances. Appraise them from the ideal point of view. As you do this you will gradually transform your whole existence for the better. These are the means whereby you may steadily promote your welfare and advancement.
As you train yourself to mentally look for the good, you will move towards the good; and, as you form higher and larger conceptions of the good, these elements will begin to find expression in your words, acts, character, person, talents, powers, attainments, and achievements; that is, all things in your life will commence to improve as the direct result of your improved thinking.
This process does not imply, however, that you are to ignore the wrongs of life, the empty places, and the undeveloped states of being; but that you are to think right through and beyond them towards the hidden good or the principle within that is ever seeking a higher and fuller expression. You will, therefore, cease to condemn and to criticize in a destructive manner; instead you will seek to bring out the good in yourself and in others, and to discover and develop the greater possibilities everywhere.
