Great Mental Laws 5.
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. This universal law is symbolized in nature by the bird. A bird has two wings, neither more nor less, and they must both be functioning before he can fly.
