In a dream a voice may be heard, or a message given in letters. This is the higher vision. The 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. It does not for one moment think, even in sleep, that it can act independently of their will. And so whatever their soul sees, it shows exactly as it is seen. They see visions even while awake, because their consciousness is not bound to this earthly plane. It is awake upon the higher planes.
