Combination of pain and pleasure is a concept that brings together two important feelings in life. Pain and pleasure complement each other. Life's happiest moments are only fulfilled when we experience pain. Moments of joy become more precious because of pain. When we go through difficult times in life, the feeling of joy deepens. Pain increases our strength and endurance, and pleasure strengthens our morale. The combination of these two feelings brings out the true nature of our lives and enriches our experience.
