There is, of course, a corollary to this. There are those who've had profound spiritual experiences, who have resolved the great questions of "what is self?" and "what is life and death?," and have awakened to the true nature of the universe, but who are not themselves charismatic or necessarily attractively calm, centered, and self-assured. Their experience and their practice will not make them into someone else, into someone who is charismatic and attractively calm, centered, and self-assured, and ignorant people caught up in the surficial appearances of things will not listen to them. "That can't be a teacher," they think. "That person is unattractive and isn't in great physical shape. That person isn't caring for their own body, and obviously isn't hydrating and exfoliating properly."
That person may talk funny, or that person may have quirks in their personality, or even a different sexual orientation. The ignorant, caught up in the surficial appearances of things, wouldn't even recognize the Buddha when she held the door open for them.
Emperor Wu didn't recognize who Bodhidharma was even when the patriarch was standing in his court and speaking the truth to the Emperor, and Wu regretted his mistake for the rest of his life.
