Every work that we do, every movement of the body, every thought that we think, leaves such an impression on the mind-stuff, and even when such impressions are not obvious on the surface, they are sufficiently strong to work beneath the surface, subconsciously. What we are every moment is determined by the sum total of these impressions on the mind. What I am just at this moment is the effect of the sum total of all the impressions of my past life. This is really what is meant by character; each man’s character is determined by the sum total of these impressions.
If good impressions prevail, the character becomes good; if bad, it becomes bad. If a man continuously hears bad words, thinks bad thoughts, does bad actions, his mind will be full of bad impressions; and they will influence his thought and work without his being conscious of the fact. In fact, these bad impressions are always working, and their resultant must be evil, and that man will be a bad man; he cannot help it. The sum total of these impressions in him will create the strong motive power for doing bad actions. He will be like a machine in the hands of his impressions, and they will force him to do evil.
Similarly, if a man thinks good thoughts and does good works, the sum total of these impressions will be good; and they, in a similar manner, will force him to do good even in spite of himself. When a man has done so much good work and thought so many good thoughts that there is an irresistible tendency in him to do good in spite of himself and even if he wishes to do evil, his mind, as the sum total of his tendencies, will not allow him to do so; the tendencies will turn him back; he is completely under the influence of the good tendencies. When such is the case, a man’s good character is said to be established.
