4.39

二、明治內外貪欲煩惱，煩惱病發如前說，若欲治之，當教作初背捨等觀，諦觀內身不淨，破壞可惡，即破緣內貪愛，復當如前，觀外不淨可惡，即離外境貪愛，即是初背捨，以是不淨心觀內外色，能破內外愛著貪婬之病。

Second, explaining the treatment for afflictions of internal and external greed and desire: the symptoms of the affliction disease are as explained before. If one wishes to treat it, one should teach the practice of the contemplation of the first liberation and so on, carefully contemplating the internal body as impure, decaying, and repulsive, which shatters greed and attachment conditioned upon the internal; furthermore, as before, one should contemplate the external as impure and repulsive, which separates one from greed and attachment to external objects. This is the first liberation: using this impure mind to contemplate internal and external form can shatter the disease of lustful greed attached to the internal and external.
