The highest realm is like the nature of water, which benefits all things without striving for fame and wealth. The four words "The highest good is like water" come from Laozi's Tao Te Ching: "The highest good is like water. Water is good for all things without fighting, and it is almost in the way of the Tao. Living in a good place, the heart is good for the abyss, with good benevolence, good words, good faith, good governance, good deeds, and good times. The only way to do things is not to fight, so there is nothing special."
Detailed explanation:
The highest good is like water. Water is good at helping all things without competing with them. It stays in a place that people don't like, so it is close to Tao. The best people should live like water, be content with being humble, have a deep heart like water, make friends like water, make friends like water, talk like water, act like water, be organized like water, do things like water, and act like water. It is because he is like water, which is free from all things, that he has no worries.
