Could moss oxidate is a question of the cliff.
Seems we have lichen the oxide color of rock
Or a moss gathers no grass green but brown.
Imagine rocks rusting like our good old gate.
Their ancient sun does not make chlorophyll
But copper brown leaves, pearl-drops of rain.
The sun may be rusting of old age in the hills.
It is not the sun alone who is rusting , in case.
The monks are doing the same thing in ocher.
Their white curls emerge from the rust brown
Clothes with Buddha peace prevailing in folds.
As they walk rust prevails in higher echelons.
