Even from a material point of view the strength which enables a person to stand on the earth, on this ever-moving earth, is not his mechanical body; it is his will. If he lost his will which holds his body man could not stand on the earth. Not knowing what the will is nor where it is, we very often overlook its existence in us and become absorbed in the causes that are outside us, causes of all the things that bring us joy and distress. The outer conditions move the spirit, and the condition of the spirit moves the outer conditions of life. Never, therefore, be surprised that good luck and ill luck rise and fall; both are directed by the will behind them. But man, accustomed to look at everything according to logic and reason, sees them in a different form from what they actually are. The saints and the wise therefore wish to find this faculty which is called the will; and on finding it they work with it. And when one becomes able to work with it properly one gains mastery over it.
