Tao Te Ching Chapter 52
There was a beginning of the universe
Which may be regarded as the Mother of the Universe.
From the Mother, we may know her sons.
After knowing the sons, keep to the Mother.
Thus one's whole life may be preserved from harm.
Stop its apertures,
Close its doors,
And one's whole life is without toil.
Open its apertures,
Be busy about its affairs,
And one's whole life is beyond redemption.
He who can see the small is clear-sighted;
He who stays by gentility is strong.
use the light,
And return to clear-sightedness -
Thus cause not yourself later distress.
- This is to rest in the Absolute.
