What is the emotion and moral that Shi Tiesheng said at the end of this passage? Seeking originality

As a disabled person, the author described a lot of suffering in the front. At the most arrogant age of his life, he lost his legs. What he lost with his legs was the ideal he was about to realize, but he survived strongly, because for Shi Tiesheng, who knew life and death like the back of his hand, "death is not a thing that needs to be rushed for success, because death is an inevitable festival", so he is not afraid of anything. "The rest is how to live." In the materialistic and ever-changing secular world, the author found an altar to wash the soul and meditate. "Fifteen years later, I will still go to that ancient garden, sit quietly under its old tree, or beside the barren grass or decaying walls, push away the noisy thoughts in my ears and catch a glimpse of my soul." The altar is the soil for his thoughts and his reflection on life.
