Every thought is made up of two factors, knowledge and feeling. A thought consists of a piece of knowledge with a charge of feeling, and it is the feeling alone that gives power to the thought. No matter how important or magnificent the knowledge content may be, if there is no feeling attached to it nothing will happen. On the other hand, no matter how unimportant or insignificant the knowledge content may be, if there is a large charge of feeling something will happen.
It makes no difference whether the knowledge content is correct or not as long as you believe it to be correct. Remember that it is what we really believe that matters. A report about something may be quite untrue, but if you believe it, it has the same effect upon you as if it were true; and that effect again will depend upon the quantity of feeling attached to it.
When we understand this law we see the importance of accepting the truth with joy in every phase of our experience.
