That's a waste of time. If you really understand Zen... you can use any book. You could use the Bible. You could use Alice in Wonderland. You could use the dictionary, because... the sound of the rain needs no translation.
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.
Ay! says the Vedanta, it is not the fault of God that this partiality exists, that this competition exists. Who makes it? We ourselves. There is a cloud shedding its rain on all fields alike. But it is only the field that is well cultivated, which gets the advantage of the shower; another field, which has not been tilled or taken care of cannot get that advantage. It is not the fault of the cloud.
External heat and cold had little influence on Scrooge. No warmth could warm, no wintry weather chill him. No wind that blew was bitterer than he, no falling snow was more intent upon its purpose, no pelting rain less open to entreaty.
If you sleep, Desire grows in you Like a vine in the forest. Like a monkey in the forest You jump from tree to tree, Never finding the fruit - From life to life, Never finding peace. If you are filled with desire Your sorrows swell Like the grass after the rain. But if you subdue desire Your sorrows shall fall from you Like drops of water from a lotus flower.
It blows a snowing gale in the winter of the year;
The boats are on the sea and the crews are on the pier.
The needle of the vane, it is veering to and fro,
A flash of sun is on the veering of the vane.
Autumn leaves and rain,
The passion of the gale.
The heavy rain beat down the tender branches of vine and jessamine, and trampled on them in its fury; and when the lightning gleamed, it showed the tearful leaves shivering and cowering together at the window, and tapping at it urgently, as if beseeching to be sheltered from the dismal night.
The holy heaven yearns to wound the earth, and yearning layeth hold on the earth to join in wedlock; the rain, fallen from the amorous heaven, impregnates the earth, and it bringeth forth for mankind the food of flocks and herds and Demeter's gifts; and from that moist marriage-rite the woods put on their bloom.
