A beautifully crafted paper, after passing through the skilled hands of a paper cutter and scissors, is folded, hammered, and cut with various techniques, emphasizing the importance of 'no' in creating art. Just like in life, we need both 'yes' and 'no' to make things meaningful. Think of a house with doors and windows, or a vase with empty space to hold flowers. Having 'yes' enables us to have more 'no'. Water in a reservoir shouldn't be overflowing; at the right time, opening the gates to water the crops, irrigate the land, and nurture the growth of life, bringing about vigor and prosperity. This is the wisdom of the old man in the story.
