Really? I'm flattered! To me it's just a simple description of what I'm guessing something might be supposed to refer to, but if it's sufficiently non-obvious to others...
Well, I haven't kept a list, but here's another that comes to mind. Someone's signature was "How do you prepare for death? Learn to live. How do you learn to live? Prepare for death."
On the face of it, this is a trollish non-answer. However, there is a way to interpret it. The first sentence is straightforward: Death is going to happen, how do I prepare for it? The second sentence is saying: You can't stop it, so the best you can do is figure out what to do with the life that you have. The third sentence is also straightforward: How do I figure out what to do with my life? The fourth sentence is saying: Imagine you're going to die, figure out your obligations that you'd want to fulfill before you die, fulfill them now, and then you will have freedom to focus on exploring what you really want to do. The phrases "prepare for death" and "learn to live" are each used twice, with different intended meanings each time.
There is always the possibility of getting a quote that is actually nonsense and was meant as nonsense (or, today, was generated by a computer), and "interpreting" wisdom into it that comes from the interpreter rather than from the quote. Or there could be multiple, similarly wise-seeming interpretations. For example, I could have interpreted the fourth sentence instead as: Imagine you're going to die; then, from that perspective, observe which things seem important and which no longer seem so important; thus, the thought-exercise of imagining you'll die is an exercise that teaches you how to live.
It's possible that cryptic sayings were devised to hold wisdom. It's also possible that they were devised by trolls surrounded by gullible admirers. Perhaps there were wise people who, as an apparently necessary evil, made themselves look cryptically impressive so as to attract funding from gullible rulers, or to keep their ideas from being misused by outsiders who might have bad intent. Perhaps there was a mixture of trolls and well-intentioned wise people. I really don't know.
I am generally a fan of straightforward textbook explanations that don't play word games, or, if they do, they have straightforward explanations of the word games. Still, it is possible that there's something to the cryptic stuff. And so it can be a fun game to try to get meaning from them.
