What does it mean, 'inner' and 'outer'?
In hex.23 Earth shows itself as the facts of reality (Mountain). Life means death has to exist as well. Growth means decay will also happen. They form the severity of life, but if you heed them, life can be rich.
It is not easy, cutting away something pretty which will be harmful if it can go its course. Accepting loss or having to decide what should be cut away are difficult decisions, but without them life will deteriorate. Holding on to what has been can suffocate the present. Letting go what will make a mess in the future will save that future.
The 'Great Image' says: The mountain depends on the earth, Bo. The high ones make their house peaceful by generosity to the low ones.
Hex.23 is the contrast of 43, proclaiming your opinions. In 23 you have to be generous to who or what supports you, in yourself and around you. It is the bases of your life and everything you do. The way a farmer tends to his field, both severe and nurturing. Weed and prune when necessary, or else it will be done to you. Give ideas a chance to come to fruition and lead them to results.
Lay bare what is in or behind things. It is dangerous when on the outside it seems all quiet and fine, and one does not know the inside.
And when things do not work the way they should, then find out if there is something rotten behind the scene.
And also: the outside of things decays some day, but if there is a strong and true inside, this will survive and find a new form. The ripe fruit of the top line is not eaten, it will rot away. If there is a noble inside - the seeds - it is an improvement or progress. If there is no good inside - the small man, no seeds - it falls apart and nothing remains.
