The Discourse on Perception of Visible Forms
307.
At Sāvatthī.
"Perception of visible forms, monks, is impermanent, subject to change, becoming otherwise;
Perception of sounds...
Perception of odours...
Perception of flavours...
Perception of tangibles...
perception of mental phenomena is impermanent, subject to change, becoming otherwise.
Whoever, monks, thus believes in and resolves upon these phenomena, this one is called a faith-follower... etc.
headed for the highest enlightenment."
