Where does rain come from? It comes from all the dirty water that evaporates from the earth, like urine and the water you throw out after washing your feet. Isn't it wonderful how the sky can take that dirty water and change it into pure, clean water? Your mind can do the same with your defilements if you let it.
Poetry and music I have banished,
But the stupidity
Of root, shoot, blossom or clay
Makes no demand.
I bend my body to the spade
Or grope with a dirty hand.
But it is at home and not in public that one should wash ones dirty linen.
[Fr., Car c'est en famille, ce n'est pas en public, qu'un lave son linge sale.]
