太阳
Teaching is the most glorious profession under the sun.
The stars shall fade away, the sun himself grow dim with age, and nature sink in years; but thou shalt flourish in immortal youth.
The teacher is the sun, the student is the moon. The teacher shines, and the student reflects.
The human being is a sun; and the senses are his planets.
