Kasan, a Zen teacher and monk, was to officiate at a funeral of a famous nobleman.
As he stood there waiting for the governor of the province and other lords and ladies to arrive,
he noticed that the palms of his hands were sweaty.
The next day he called his disciples together and confessed he was not yet ready to be a true teacher.
He explained to them that he still lacked the sameness of bearing before all human beings,
whether beggar or king. He was still unable to look through social roles and conceptual identities
and see the sameness of being in every human. He then left and became a pupil of another master.
He returned to his former disciples eight years later, Enlightened.
