A person always takes virtue to be virtue in action, sin to be sin in action, never thinking about virtue and sin in speech or thought. Sometimes man's thought is stronger than his speech or action. It is the experience of every mystic and every person who has trodden the path, that the power of thought is much greater than that of speech or action. In our everyday life we often find that if we think of a person bringing a certain book or flower we desire, he comes to see us, bringing this book or flower with him. We had not expressed the desire, and yet it has been fulfilled. Such is the power of thought, the creation of mind. "Thoughts are things", it has been said. But they are more; thoughts are beings. They are as much living beings as we are; they work as we work; they have life in them. The body can generate, but the mind can generate too, it is the generation of the mind which we call thought or imagination. Thought is controlled, whereas imagination is not.
