Previously I remarked that the puzzle is a closed system and all the knowledge you need to solve it is within itself.
If you are stuck on a certain part you can work on an entirely different part because they’re all connected and sorting out one part will automatically sort other parts so I believe that with this virus I might be wrong.
So we could compare that to human life and if you can’t solve a problem in one part of your life leave it alone for a time and work on something else that you can change or improve or that will make you feel happier and when you go back to the original problem you may find that it’s disappeared or it’s easier to do with
Of course you can’t compare the complexity of a human life to this simplicity of these puzzles but nevertheless one can meditate and learn from them. After all they’re not much use in other ways.
I don’t like things that are not much use unless they are ornamental and beautiful and I don’t really think I could say that about these puzzles.
How my heart sings 
I find that life is sufficient puzzle in itself that I’m reluctant to engage with artificial puzzles

Sometimes we can draw analogies between things we learn from simple puzzles and how we can deal with more complex puzzles.
