3.41

[The Master] cited: A monk asked Fayan: “The two words ‘sound’ and ‘form’—how can one penetrate them?” Fayan said: “If the great assembly understands where this monk is asking, penetrating sound and form will not be difficult either.”
The Master said: “Previously not understanding was only because thieves of the household are hard to guard against. Directly clear right now, for the time being dwell in a thatched hut.”
