Man as mind is subject to change. He is not something "made" and finally completed, but has within him the capacity for progress.
APRIL THIRD
THE purification of the heart, the thinking of right thoughts, and the doing of good deeds—what are they but calls to a higher, nobler mode of thought energising forces urging men to effort in the choosing of thoughts which shall lift them into realms of greater power, greater good, greater bliss?
Aspiration, meditation, devotion—these are the chief means which men in all ages employ to reach up to higher modes of thought, wider airs of peace, vaster realms of knowledge, for as he thinketh in his heart, so is he; he is saved from himself—from his own folly and suffering by creating within, new habits of thought; by becoming a new thinker, a new man.
Man’s being is modified by every thought he thinks. Every experience affects his character.
