The Discourses on Desire for the External as Suffering and so on

180-182. "Whatever, monks, is suffering, therein your desire is to be abandoned, lust is to be abandoned, desire and lust is to be abandoned. And what, monks, is suffering? Visible forms, monks, are suffering; therein your desire is to be abandoned, lust is to be abandoned, desire and lust is to be abandoned. Sounds... Odours... Flavours... Tangibles... Mental phenomena are suffering; therein your desire is to be abandoned, lust is to be abandoned, desire and lust is to be abandoned. Whatever, monks, is suffering, therein your desire is to be abandoned, lust is to be abandoned, desire and lust is to be abandoned."
