The Tao is like an empty bowl, yet it may be used without ever needing to be filled.
This was a hard one for me. I spent quite a bit of time thinking about it. Foolish old man. Only after I gave up did it rise to conciousness. So here it is.
You might think the glass is half empty
You might think the glass is half full
But neither is close to the truth
For in reality
There is no glass
There is no water
There is no thinking
There is no you
There is only the empty bowl
