In my oppinion it have to do with "to create".
We are on the way to get old till the end of body.
Nature of beeing will go these way. And nature of beeing alow or prohibitit whats against these way. Human beeing is in a way
a strong living creation, that we have only sickness, ourself and accidents as enemys, like the wales in water and the elefant on land, before
human beeing come up. Everything work in this case, espacially alowing and prohibitation from humans for (other) humans.
And if we archive a spirit that the most (highest part of dieyin from) can get old, that the body want to pass away,
after a liveble life. Than we are crown of spirit in beeing.
Last but not least a creation (spiritual) in this way, "Me myself and I" from "De La Soul", bump it arround, if u want.
