The lamp produces two things: light and shadow. The light is generated by the lamp's flame. But no lamp can burn without a vessel to hold its fuel and wick; hence the shadow cast by the lamp, by its vessels partial obstruction of the flame's light.

Man is comprised of body and soul. The soul could not shed its light were the body not to hold it as a lamp holds its flame. But this material containment also eclipses the sou'ls light, imparting darkness and shadow to our lives.

Yet shadow, in its own way, can be as illuminating as light: projecting the opaque areas of self onto the canvas of experience, emphasizing and defining what requires correction and development in our lives.
