If you ever hear yourself saying, 'I think I understand this,' that means you don't.

If you can't explain it simply, you don't understand it well enough.

If you can't understand it without an explanation, you can't understand it with an explanation.

The trouble with your elders is, anything they didn’t understand they reinterpreted to mean something else and then thought they understood it.

Don’t try to understand! It’s enough if you do not misunderstand.

If you think it's simple, then you have misunderstood the problem.

Being able to communicate with someone doesn’t necessarily mean that you understand them.

If you understand, things are just as they are. If you do not understand, things are just as they are.
