When a drug comes in from Canada, I wanna make sure it cures ya, not kill ya... I've got an obligation to make sure our government does everything we can to protect you. And one - my worry is that it looks like it's from Canada, and it might be from a third world.
When mortals are alive, they worry about death. When they're full, they worry about hunger. Theirs is the Great Uncertainty. But sages don't consider the past. And they don't worry about the future. Nor do they cling to the present. And from moment to moment they follow the Way.
If a problem is fixable, if a situation is such that you can do something about it, then there is no need to worry. If it's not fixable, then there is no help in worrying. There is no benefit in worrying whatsoever.
