We should never try to visualize this light or make it appear. Jesus said: "The kingdom of God cometh not with observation . . . for, behold, the kingdom of God is within you." All forms of concentration that I have ever heard of do not lead to the mystical sense. They are psychological stunts. We must be very careful not to confuse these subjective phenomena with spiritual Reality. They may or may not be spiritual.

The mystics, having seen the light, have never been the same afterward, but they have been perfectly normal human beings. There was an added something, an atmosphere about them, that everyone felt. It is that atmosphere that we sense about people who are evolved spiritually, they have a sense of calm and certainty, a contact with Reality which all people arrive at to some degree. It has been the vitality of every religion, no matter what the dogmatism of its theology may have been.

So we find that people who spend a great deal of time in prayer, meditation, or communion with the Spirit gradually take on a new atmosphere, a new sweetness, a light which all people sense. As Plotinus said, this is a gift which all men have but which few men use.
