A rich man asked Master: “I have been busy making money all my life. How much should I earn before I stop?”
Master put a cup on the table and filled the cup with a large pot of tea.
The tea overflowed over the table, then the master continued to pour until the whole pot of tea was empty.
Master asked: “Do you understand?”
The rich man said: “I don’t understand what this means?”
Master said: “The whole pot of tea is the money you earned in your life. The capacity of the cup is the money you need to spend in your life. Making more than the wealth you need will only overflow and cannot be retained. ”
