It may be asked if I can prove these statements；and without going into details，I answer that I can do so，both by logic and experience.
Reasoning back from the phenomena of form and thought，I come to one original thinking substance；and reasoning forward from this thinking substance，I come to man＇s power to cause the formation of the thing he thinks about.
And by experiment，I find the reasoning true；and this is my strongest proof.
If one man who reads this book gets rich by doing what it tells him to do，that is evidence in support of my claim；but if every man who does what it tells him to do gets rich，that is positive proof until some one goes through the process and fails. The theory is true until the process fails；and this process will not fail，for every man who does exactly what this book tells him to do will get rich.
I have said that men get rich by doing things in a Certain Way；and in order to do so，men must become able to think in a certain way.
A man＇s way of doing things is the direct result of the way he thinks about things.
To do things in a way you want to do them，you will have to acquire the ability to think the way you want to think；this is the first step toward getting rich.
To think what you want to think is to think TRUTH，regardless of appearances.
Every man has the natural and inherent power to think what he wants to think，but it requires far more effort to do so than it does to think the thoughts which are suggested by appearances. To think according to appearance is easy；to think truth regardless of appearances is laborious，and requires the expenditure of more power than any other work man is called upon to perform.
There is no labor from which most people shrink as they do from that of sustained and consecutive thought；it is the hardest work in the world. This is especially true when truth is contrary to appearances. Every appearance in the visible world tends to produce a corresponding form in the mind which observes it；and this can only be prevented by holding the thought of the TRUTH.
To look upon the appearance of disease will produce the form of disease in your own mind，and ultimately in your body，unless you hold the thought of the truth，which is that there is no disease；it is only an appearance，and the reality is health.
To look upon the appearances of poverty will produce corresponding forms in your own mind，unless you hold to the truth that there is no poverty；there is only abundance.
To think health when surrounded by the appearances of disease，or to think riches when in the midst of appearances of poverty，requires power；but he who acquires this power becomes a MASTER MIND. He can conquer fate；he can have what he wants.
This power can only be acquired by getting hold of the basic fact which is behind all appearances；and that fact is that there is one Thinking Substance，from which and by which all things are made.
Then we must grasp the truth that every thought held in this substance becomes a form，and that man can so impress his thoughts upon it as to cause them to take form and become visible things.
When we realize this，we lose all doubt and fear，for we know that we can create what we want to create；we can get what we want to have，and can become what we want to be. As a first step toward getting rich，you must believe the three fundamental statements given previously in this chapter；and in order to emphasize them. I repeat them here：
There is a thinking stuff from which all things are made，and which，in its original state，permeates，penetrates，and fills the interspaces of the universe.
A thought，in this substance，produces the thing that is imaged by the thought.
Man can form things in his thought，and，by impressing his thought upon formless substance，can cause the thing he thinks about to be created.
You must lay aside all other concepts of the universe than this monistic one；and you must dwell upon this until it is fixed in your mind，and has become your habitual thought. Read these creed statements over and over again；fix every word you＇re your memory，and meditate upon them until you firmly believe what they say. If a doubt comes to you，cast it aside as a sin. Do not listen to arguments against this idea；do not go to churches or lectures where a contrary concept of things is taught or preached. Do not read magazines or books which teach a different idea；if you get mixed up in your faith，all your efforts will be in vain.
Do not ask why these things are true，nor speculate as to how they can be true；simply take them on trust.
The science of getting rich begins with the absolute acceptance of this faith.
