Light is not a thing. It is a being, who is a (meta)way. A (meta)way is neither a mere path, nor a method. It is a way of generating endless methods which are paths.

To understand this correctly, you must personally establish contact with light. Our ancestors were adept at this, but we, the children of science, cannot hope to imagine such an experience. Words and books will lead you astray. Go, in person. Make contact. Please.
