Be not hasty and rushed for things that have yet to come to pass.
Do you think it is wise to pick fruits before they become ripe? Tomorrow is non-existent, having no reality today, so why should you busy yourself with it? Why should you have apprehensions about future disasters? Why should you be engrossed by their thoughts, especially since you do not know whether you will even see tomorrow?
The important thing to know is that tomorrow is from the world of unseen, a bridge that we do not cross until it comes. Who knows, perhaps we might never reach the bridge, or the bridge might collapse before we reach it, or we may actually reach it and cross safely.
