The world is in darkness. There is light within which others can sense.
The world is full of darkness, but the darkness really isn't the world -- it's your own mind. The eye is the opening to the mind; the eye is the lamp of the body. If your eye is good, your whole body is good, is full of light; but if your eye is bad, your whole body bad, is full of darkness.
This is not the physical eye; this is the spiritual eye. And if your eye is alive with goodness, with spiritual goodness, with spiritual light, then your whole body is full of light; and the whole world will be full of light -- at least as far as you're concerned.
Others who see you will know there is something very special about you, as they sense the light that is within you. They will not to understand; they just know that there is something different about you; there is something fresh and clean about you, something that can be trusted, something that is lacking in others.
The eye of light is not visible to the physical eye; but people who have any awareness, even the most minuscule awareness of the spiritual world -- will detect this spiritual light. They will be drawn automatically to you because they will see you as a teacher, as one who knows, as one who understands.
Light Is Life!
