“The sun,--the bright sun, that brings back, not light alone, but new life, and hope, and freshness to man--burst upon the crowded city in clear and radiant glory.” ― Charles Dickens, Oliver Twist.

The day the sun gets covered with clouds, it is unable to visibly rise. Have you observed how we feel lethargic that day? The Sun, to me represents warmth and energy to carry out our daily tasks.
