How ironic. One is noble for not being noble. What is the lightening flash, what is the thunder. There is a silent thunder in this haiku. Lightening burns away the oxygen and when the surrounding air rushes in to fill the vacuum, you have thunder. Satori or realization of Oneness— where there once was two— is a lightening flash in consciousness; but to find something there would normally be the thunder where one shouts: I have found it! Eureka, I’am awake! That is the expected thunder, but here there is no thunder, so the thunder is silent.
One finds no satori in the lightning flash because in that flash of awakening, there is no finder and no satori. There is not two in the flash, so there is nothing to be found. Not even the memory is to be found. As the Zen master says: if you see the Buddha on the road, kill him. If you see Satori on the road, kill it.
There is nothing to be found in the lighting flash because it doesn’t last. The night is lit up for an instant and the earth around you is revealed. Then darkness returns after the flash, leaving with its imprint on your mind.
When satori lasts, however, everything stays the way it always already is, only now you see it just what is. Nothing is changed. There is nothing to be found.
