There was a little monk in a temple whose job was to sweep the fallen leaves from the courtyard every morning, a task that required a great deal of time.
During the autumn and winter, this task became particularly troublesome for him. He thought hard every day, searching for ways to make the work easier, and even sought advice from his fellow monks.
When the abbot learned of this, he called the little monk for a talk. The little monk honestly shared his thoughts. The abbot suggested, "Before you sweep tomorrow, try shaking the trees vigorously to bring all the leaves down at once. That way, you won't have to sweep the following day."
The little monk thought the abbot was incredibly clever; he had been thinking about this for so long but never came up with such an idea. Early the next morning, without even washing his face, he rushed to the backyard and shook the trees with all his might, hoping to clear both today's and tomorrow's leaves in one go. After he felt he had done enough, he swept the leaves and went to eat happily.
However, the next day, when he arrived in the courtyard, he was stunned: all his efforts from yesterday had been in vain, and the ground was once again covered in fallen leaves.
The abbot approached him and said, "Do you know why I gave you that suggestion? I wanted you to understand that no matter how much effort you exert today, tomorrow's leaves will still fall." The little monk finally understood that many things in life cannot be bypassed; living earnestly in the present is the only true way to live.
