Arana Vibhanga Sutra 9.5:
In the Arana Vibhanga Sutra, the Buddha says, “Thus, bhikshus, do we know there are the dharmas of passion (rana) and no passion (arana). You monks must understand the dharmas of passion and no passion but must practice the path of no passion. No other practice is possible. Moreover, fellow monks, the noble son Subhuti is such a one who practices freedom from passion.”
