Heaven exists for eternity, and there is no distinction between high and low.
Because of the existence of people, they gradually know the difference between high and low.
Man created order, created rules, and created classes.
This class, collectively known as society.
Society is an ideology of life-prolongation composed of people, in which political groups and social groups will appear, and at the current stage of civilization development, all groups will revolve around political groups.
Individual people, because of different knowledge, different experiences, fixed classes, the "heaven" they see, are also different, and this "heaven" is the vision.
"Sitting in the well and watching the sky" and "summer insects cannot speak of ice" these are all different visions, and it can also be said that it is no longer a problem of vision, but a problem of cognition, a problem from zero to one.
You haven't seen it, you haven't experienced it, it's hard to have that kind of cognition.
Lao Tzu said that the dream in the text of "eating willingly, serving beautifully, living in peace, and enjoying its customs" will only be realized after a thousand years, which is the vision of a thousand years.
It has nothing to do with ordinary people, although it involves a lifetime. You and I are also three or five kilometers away from showing off the magnates and faces.
A hundred miles away, a thousand miles away, you and I are ordinary people.
People, the greatest progress, is to broaden their horizons.
The greatest happiness of people is the happiness of taking a step forward, whether it is self or future generations.
