This is how the Self speaks.
How does the Mountain speak? It speaks with gravity, with the difficulty of an uphill passage. It speaks with rocks that can make you lose your balance, or with pebbles that slide under your shoe then tumble away producing a slip from which you easily recover, but which costs you time and energy. The mountain speaks with changing weather, with heights each having its own character. It has shadow side and sunny side, a windy or calm side. Sometimes the mountain addresses you merely by its inexpressible beauty.
As you climb both beauty and gravity together take your breath away.
