Here’s an interesting quote by Charles Haanel:

“You may freely choose what you think, but the result of your thought is governed by an immutable law! Is not this a wonderful thought? Is it not wonderful to know that our lives are not subject to caprice or variability of any kind? That they are governed by law. This stability is our opportunity, because by complying with the law we can secure the desired effect with invariable precision.

It is the Law which makes the Universe one grand pan of Harmony. If it were not for law, the Universe would be a Chaos instead of a Cosmos.

Here, then, is the secret of the origin of both good and evil: this is all the good and evil there ever was or ever will be.

Let me illustrate. Thought results in action. If your thought is constructive and harmonious, the result will be good: if your thought is destructive or inharmonious, the result will be evil.

There is therefore but one law, one principle, one cause, one Source of Power, and good and evil are simply words which have been coined to indicate the result of our action, or our compliance or non-compliance with this law.

The importance of this is well illustrated in the lives of Emerson and Carlyle. Emerson loved the good and his life was a symphony of peace and harmony; Carlyle hated the bad, and his life was a record of perpetual discord and inharmony.

Here we have two grand men, each intent upon achieving the same ideal, but one makes use of constructive thought and is therefore in harmony with Natural Law, the other makes use of destructive thought and therefore brings upon himself discord of every kind and character.

It is evident therefore that we are to hate nothing, not even the “bad,” because hatred is destructive, and we shall soon find that by entertaining destructive thought we are sowing the “wind” and shall reap the “whirlwind.””
