The Tao that can be spoken is not the eternal TaoThe name that can be named is not the eternal name
The nameless is the origin of Heaven and Earth
The named is the mother of myriad things
Thus, constantly without desire, one observes its essence
Constantly with desire, one observes its manifestations
These two emerge together but differ in name
The unity is said to be the mystery
Mystery of mysteries, the door to all wonders
This translation was taken from Taoism.net. A site I reccomend you check out. The Tao is not a religion so much as it is a way of life. Loosely translated the Tao is the way.
This first chapter I feel states that you cannot name or fully describe the Tao rather Tao must be experienced without labels but that the hugest mystery is the bridge between our need to understand and be able to explain the Tao and actually experiencing the Tao without words.
The website gives a much better explanation here.
I will continue to share chapters from the Tao Ching as I experience them.
