No Meng Po Soup

Is there any Meng Po soup? "The No-Phase Stanza" says, "The body is like a Bodhi tree, and the mind is like a mirror stand. I should brush it diligently at all times to prevent it from stirring up dust." "The Sixth Patriarch's Altar Sutra" says, "Bodhi has no tree, and the mirror is not a stand. There is nothing in the beginning, so how can it attract dust?" What's the truth? The article is written by oneself.
