This is a kind of complex ten-character proverb composed by Zhuge Liang about 1800 years ago. The proverb means "Leading a simple life will yield a clear mind, and having inner peace will help you see far (into the world)".What I have translated as "simple life" means NOT being materialistic and NOT competing in the rat race.The last word means "far", but the deeper meaning is that you will surpass what you can currently see or understand. Perhaps even the idea of opening up vast knowledge and understanding of complex ideas.The whole phrase has a theme that suggests if you are NOT an aggressive cut-throat person who fights his way to the top no matter how many people he crushes on the way, and instead seek inner peace, you will have a happier existence and be more likely to understand the meaning of life.
