Light can exist only if darkness exists. Without darkness there will be no light, so those who love light and hate darkness are in a dilemma. Life cannot exist without death. It is death that creates the space for life to exist. This is a great insight, that death is the contrast, the background, the blackboard on which life is written with white chalk.
Death is the darkness of night on which life starts twinkling like stars.
If you destroy the darkness of the night the stars will disappear. That's what happens in the day. They are still there, but because there is too much light you cannot see them. They can be seen only in contrast. The saint is possible only because of the sinner.
