Watching them at leisure is like reading the best essay of the Universe. Be a little unwitty and stay away from astuteness, save some righteousness for the world. Rid of extravagance and lead a simple life, save an untainted name in history. Music, books, poems, and paintings cultivate a scholar's mind, whilst a common fellow only enjoys the superficiality. Mountains, rivers, clouds, and scenary enrich an intellectual's knowledge, yet an ordinary person only appreciates the image.
Nothing defines anything.
It is all subject to one's comprehension. So, to pursue knowledge, one needs to have insights.
