There were a grandpa and his grandson who woke up early to study every morning.
One day, the grandson asked: “Grandpa, I read like you every day, but I don’t understand it, and I forget everything when I close the book. Is it useful to read this way?”
Grandpa didn’t say a word. He turned around and took a bamboo basket that usually holds black coal and handed it to his grandson: “Go and bring me a basket of water.”
The boy tried many times, but every time the water leaked before he ran home.
Seeing the exhausted grandson, grandpa smiled and pointed to the bamboo basket. Only then did the grandson realize that the bamboo basket was different from before, that it has become clean from the inside out.
Reading more, even if you don’t understand or remember, will change you subtly, in your appearance or in your heart.
As the old saying goes, there is no useless work in the world, nor is it empty to draw water from a bamboo basket.
