The idea of Zen is to catch life as it flows. There is nothing extraordinary or mysterious about Zen. I raise my hand ; I take a book from the other side of the desk ; I hear the boys playing ball outside my window; I see the clouds blown away beyond the neighbouring wood: — in all these I am practising Zen, I am living Zen. No wordy discussions is necessary, nor any explanation. I do not know why — and there is no need of explaining, but when the sun rises the whole world dances with joy and everybody’s heart is filled with bliss. If Zen is at all conceivable, it must be taken hold of here.
