Our true buddha-nature has no shape. And the dust of affliction has no form.
And as long as you're subject to birth and death, you'll never attain enlightenment.
Don't hate life and death or love life and death. Keep your every thought free of delusion, and in life you'll witness the beginning of nirvana, and in death you'll experience the assurance of no rebirth.
Once you see your nature, sex is basically immaterial.
In order to see a fish you must watch the water
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.
