original interpretation . . .
Spirit of the valley is immortal.
It is called the mystic nature.
The gate o f the mystic nature is regarded as the root of the universe.
It is everlasting and cannot be consumed.
my interpretation . . .
The Yin mother never dies.
Her home is in the valley.
Her womb is the birth place of all things, it will never dry up.
Mother Yin eternally woos Father Yang from his place of light upon the mountain top.
For it’s in her valley where he plants his seed and learns the meaning of the Tao.
This endless cycle is what keeps man rooted to the Earth.
Is not the earth a school house and pathway to the gods?
