If our body really belonged to us, it would obey our commands. If we say, "Don't get old," or "I forbid you to get sick," does it obey us? No! It takes no notice. We only rent this "house," not own it. If we think it does belong to us, we will suffer when we have to leave it. But in reality, there is no such things as a permanent self, nothing unchanging or solid that we can hold on to.
