"同じ川に二度と入ることはできない、何故なら同じ川ではなく、彼も同じ人ではないからだ。"

Simplified Meaning:

Everything around us changes constantly, and we, too, are always growing and evolving. Imagine a river flowing by—a river never stays exactly the same because the water is always moving. If you put your foot in that river one day and then again the next day, the water touching your foot will be different each time. You also change over time because your thoughts, feelings, and experiences shape who you are. So when you encounter something again, it’s a new experience because you've changed, and so has the world around you. For example, think about reading a book you loved as a child. When you read it as an adult, you notice different things in the story that you didn’t see before because you now have more life experiences and different perspectives. This idea teaches us to appreciate moments and understand that every experience is unique, just like every version of ourselves at different points in our lives. It encourages us to be mindful and present, recognizing that we grow a little bit every day.
