In the darkness, two things are common to all men: fear and the desire for light.

My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all.

忧伤愁苦，就会心气滞结；忿怨愤怒，就会心气横逆不顺；惊恐畏惧，就会心气沉落不浮；拘谨固执，就会心气郁郁不释；急躁浮躁，就会心气损耗不足。

Happiness and unhappiness depend upon the opinion we have of things.

人生短暂，过着过着你就没了，明白么？
