You have a cup in front of you. When you drink water, it is a water cup; when you smoke, it becomes an ashtray; when you arrange flowers, it turns into a vase.

The cup itself is actually nothing; this is called emptiness.
What you use it for is what it truly is; this is called skillful use.
If you insist that it must be a cup, this is called attachment to form.
Because of this, you argue and debate with others, which is called ego attachment.
As a result, your arguing leads to emotions and insults, which is called affliction.
Finally, you develop aversion toward this person, which is called prejudice.
Then, you realize that in fact, there are no others in this world—only yourself.
When you are present, the world exists with you; when you leave, the world disappears with you.
Those others, those entanglements, those attachments, those controls—are all just internal conflicts and entanglements you create within yourself.
And so, you understand again the saying: "Originally, there is nothing at all; where can dust settle?" $BTC $ETH
