When one is lightened by the sun in morning, he or she feels cleaned up. The sunshine not only makes the sky clean, but also it makes human heart so. Recently, the number of people who is stirring until midnight and for whom it is painful to wake up in the next morning are increasing. If a family has one or two members whose heart is like the morning sun, all the family members may feel cheered up by the ones. The moon shines by reflecting the sunshine. Similarly, the sun makes itself shine, and it also makes others shine. I think that in human, a self not only shines alone, but it also has the power of lightening others. No one gaze at the sun. On the other hand, the sun aids human in gazing at the things which reflect the sun. People regard the role of the sun not as shining alone but as lightening things around the sun. I think that making others shine is superior to shining alone. It's said that the sun illuminates even the bad. I think that, in the case of human, it's similar. Your joyous life is possible by your endeavor of lighting people around you. I think real joviality is to encourage others to do something.
