The world is a world of phenomena, filled with errors, ignorance, and contingencies, where people and things constantly change. After daily interactions with a vast number of external people and things, our souls often feel exceptionally weary. If you cannot see what drives these phenomena, or if you do not understand the underlying mechanisms, you will find yourself overwhelmed by the complexity of appearances. Therefore, let us seek to understand the principles and essences of things. When you view the world from a holistic and essential perspective, you will no longer be deceived by superficiality. Gradually, you can detach yourself from this world of appearances and live with a more contemplative mindset; the more you observe, the clearer the truth of this world becomes.
