One who knows does not talk about it.
One who talks about it does not know.
Stay quiet.
Keep inside.
Blunt sharpness.
Unravel entanglements.
Diffuse brightness.
Merge with dust.
This is called “discovering original nature.”
One who knows original nature is
indifferent to intimacy and estrangement,
unconcerned with benefit and harm,
immune to honor and disgrace.
He is embraced by heaven.
