In a dream a voice may be heard, or a message given in letters. This is the higher vision. Sages and saints see in the vision exactly what will happen or what the present condition is, because their mind is controlled by their will; even in sleep it does not for one moment think that it can act independently of their will. And so, whatever the soul sees, the mind shows it exactly as it is seen. Sages and saints see visions even while awake, because their consciousness is not bound to this earthly plane; it is awake and acts freely upon the higher planes.
