A man came, a monk, not belonging to the Zen people. He wanted to be initiated by the master, a Zen master. He was asked, ’From where are you coming?’
He said, ’I come from a monastery which is called ”the monastery of spiritual light”.’ The master said, ’Spiritual light? Never heard about anything like that. Strange! I am ninety and I have never heard anything about spiritual light; what do you mean? In the day there is sunlight, in the night there is the lamplight. From where comes this spiritual light, what is this spiritual light?’
The man was at a loss, he couldn’t answer. Then the master answered for him. He said, ’Don’t be worried. In the day, sunlight; in the night, lamplight. This is what spiritual light is; there is no other spiritual light.’
