"A Warning to all Close minded, petty, or malicious, great and small spirits! Just as the whole plot of Parsifal of the festal play of Richard Wagner is only an allegory, a symbolical depiction with no real occurrence in the material world, so the above explanation of the Graal-secret is not to be understood as literal, personal, material, earthly, relative to vulgar events. But it is only to be understood as totally impersonal, symbolical, and relative on purely spiritual grounds."
