An hourglass is to a watch what the world is to a book...
We read the book of the world without knowing that it is the only book we are in and reading it at the same times...
We dont look at a number indicating an abstract hour with an hourglass as with a watch , we flow ourself with time, knowing that we can also "stop" time by reversing the hourglass with an act of free will... Then time may come back to his source...
Time become a superstition as the world itself become an idolatry if we forget that we read them as we wish it at the end ...
«The fact that my wife wait for me for dinner is not the result of any superstition but certainly result from some form of well placed idolatry»-- Groucho Marx 🤓
