In the practice of the Science of Being Well the will is not used to compel yourself to go when you are not really able to go, or to do things when you are not physically strong enough to do them. You do not direct your will upon your physical body or try to compel the proper performance of internal function by will power.
You direct the will upon the mind, and use it in determining what you shall believe, what you shall think, and to what you shall give your attention.
The will should never be used upon any person or thing external to you, and it should never be used upon your own body. The sole legitimate use of the will is in determining to what you shall give your attention, and what you shall think about the things to which your attention is given.
All belief begins in the will to believe.
You cannot always and instantly believe what you will to believe; but you can always will to believe what you want to believe. You want to believe truth about health, and you can will to do so. The statements you have been reading in this book are the truth about health, and you can will to believe them; this must be your first step toward getting well.
