The heavens are supreme and boundless. Yet the heavens are not the only thing in the world that is supreme and boundless. The sea? No. The earth? No. The answer is the human heart. The human heart can be supreme and boundless, or it can be narrow and small. It all depends on the person.
What does it mean to seek the heavens? The answer: to seek the supreme and boundless in the human heart. To seek the greatest goodness in people's hearts, one must first experience the suffering of all living beings, then seek the meaning of life. If you do not experience suffering or seek meaning, you will waste half a lifetime, and let a whole life go to waste. In the end, all that remains is emptiness.
