What is the sign that one is ready to awaken from sleep? It is when a person begins to think, "All that I have learned and understood seems so unreal; there are some realities of which I am vaguely aware, and yet compared with them all I have studied and done seems to be of no account." As the dawn comes after the night of darkness, so he sees light appearing; but he has not yet seen the sun; he is only beginning to awaken.
