According to Osho, a long beard has no spiritual significance; it belongs to the body, not to the being. Referring to the Zen koan 'Why doesn't Bodhidharma have a beard?', he says the insight is that the real Bodhidharma is beyond form. What you see is your projection; look again and recognize the witness within.
A beard is just hair; the real you isn’t the body, so don’t give appearances special meaning.
