Chapter 1 treats earthly life as a womb rather than a destination. The point is not to belittle embodied life, but to clarify its purpose: this life is the hidden formation stage for a later birth.
That metaphor makes moral formation feel less arbitrary. A person is not merely collecting merits or avoiding mistakes. They are developing the organs of life needed for a different environment.
It also reframes urgency. The issue is not how long one remains in the womb, but whether one is becoming ready for the world to come.
