What is true in the microcosm is true in the macrocosm. The thread-spirit holds the universe together. Dante understood this:

In the order I speak of, all natures incline
Either more near or less near to the source
According as their diverse lots assign.
To diverse harbours thus they move perforce
O’er the great ocean of being, and each one
With instinct given it to maintain its course.
This bears the fiery element to the moon;
This makes the heart of mortal things to move;
This knits the earth together into one.
Dante Alighieri ,Paradiso, Canto 1, lines 109-117
