the guru had a secret: he was a fake.
in the beginning, he pretended to be a guru as a joke, but some people did not get the joke, and they become his unironic followers.
the guru decided it had gone too far, and he stood up at the next class and confessed, “everything i have ever told you is a lie. i know no truths. i am a fraud.”
the students said, “the guru’s teachings were very thought-provoking today.”
