It was only when I got interested in photography I realized how much darkness and light need each other to be perceived. Take one of them away and we would have difficulty to see. The more contrast there is between them, the stronger we experience them. That very much reminds me of life itself. I relish the light and joyful moments in life, but the moments of challenge and darkness make the experience of light so much more intense.
One pinprick of light in the dark can guide us like a star, but one dark speck in the light would hardly be noticed. Which makes me think darkness and light are both a necessary part of life, but light is the stronger one.
