It is said that there is a primitive ancient tribe. They have been moving for a long time and have no fixed place, but they have a persistent habit of stopping for a day every two days, which will not change from generation to generation. Some people don't understand. The old tribal leader explained that our footsteps were too fast for our souls to keep up. We walked for two days and took a day off just to wait for our souls.

We walk too fast, which can be understood as the rapid development of material life.

.. the soul can be understood as some aspects of the spirit. ..

We give up the spirit for the pursuit of material things, so that the spirit can't keep up.
