Some think life is all about doing good and keeping away from evil. To them, struggle has no purpose of its own -- to have struggled is to have failed. Success, they imagine, is a sweet candy with no trace of bitterness.
They are wrong, very wrong. Struggle is an opportunity to reach the ultimate, when darkness itself becomes light. In the midst of struggle, an inner light is awakened. Light profound enough to overwhelm the darkness, encasing it and winning it over.
But if darkness never fights back, how will it ever be conquered?
Based on letters and talks of the Rebbe, Rabbi M. M. Schneerson
