Look at both the top and bottom of the world to get to know the world well; wander on the surface, but also dive deep! The best way to get to know something is to look at both the visible and the invisible parts of it!

Superficial cannot discover the deep, because both live in different levels and likewise the deep cannot meet the deepest! Change your level to reach at different levels!

For those who wander in the depths, there is nothing deep!

Don’t say deep things to shallow people and don’t talk about shallow things with the deep people!
