We all want to have eternal things, such as relationships and wealth. This kind of immutability brings us a sense of stability and security. However, changes are happening every moment without our noticing. No matter how solid something is, it will eventually dissipate, like smoke that cannot be caught. Diamonds are the hardest material on earth, and diamonds are also a metaphor for eternal and stable relationships. Even though balloons can be made to look like diamonds, they are actually light and soft. Just like what we think is eternal, it may not be the case. When you think you have it, you will ignore the passing process. Balloons, like flowers, have a blooming period, and what you see is different every moment.
