Passivity to be thrown aside

Why do you write “If I get” [aspiration]—one can always aspire. It is your mistake to think that everything must come of itself and nothing is within your own power to do. This kind of belief in the necessity of passivity to all movements should be thrown aside. Will, aspiration, surrender are things that you must do yourself—although even in doing them you must call in the Divine Power to help your will, aspiration and surrender and make them effective.
