What is this thing called the existence? Is it all the things that we perceive it to be? Or is it something else? It's a gift. One of my favorite examples is the bird in the cage. You may think that you own the bird inside the cage, but you're wrong. You only own the cage. People think that they need to have a very fancy cage, that the more incredible the cage, the more incredible the bird will look. But the cage and the bird are really two different things. When the bird is gone, all that will be left is the cage.
