I think it's super great and gives me a lot of inspiration. If you throw a bowl full of water and a stone into it, a lot of water will be spilled immediately. However, if it is a lake, a stone thrown into it will cause ripples. If it's Lake navasa or the sea, even if you dump a truckload of stones, you can't see the difference. Bowls, lakes and seas are like human realms, and stones are like setbacks and obstacles in life. The realm is like a bowl, and a small setback will crush you; The realm is like a lake, and setbacks will make you fluctuate and affect you; The realm is like the sea, and no matter how big the setback is, it will not affect you.
