Sounds are impermanent;
therein your desire is to be abandoned, lust is to be abandoned, desire and lust is to be abandoned.
Odours are impermanent;
therein your desire is to be abandoned, lust is to be abandoned, desire and lust is to be abandoned.
Flavours are impermanent;
therein your desire is to be abandoned, lust is to be abandoned, desire and lust is to be abandoned.
Tangibles are impermanent;
therein your desire is to be abandoned, lust is to be abandoned, desire and lust is to be abandoned.
Mental phenomena are impermanent;
therein your desire is to be abandoned, lust is to be abandoned, desire and lust is to be abandoned.
Whatever, monks, is impermanent, therein your desire is to be abandoned, lust is to be abandoned, desire and lust is to be abandoned."
