Our true buddha-nature has no shape. And the dust of affliction has no form.
Mortals liberate Buddhas and Buddhas liberate mortals.
But this mind isn't somewhere outside the material body of the four elements. Without this mind we can't move. The body has no awareness. Like a plant or a stone, the body has no nature. So how does it move? It's the mind that moves.
If you use your mind to look for a Buddha, you won't see the Buddha.
To find a Buddha all you have to do is see your nature.
Regardless of what we do, our karma has no hold on us.
