又涅槃經云。出家之人有四種惡病。是故不得四沙門果。何等四病。謂四惡欲。一為衣欲。二為食欲。三為臥具欲。四為有欲。有四良藥能療是病。一糞掃衣。能治比丘為衣惡欲。二乞食。能破比丘為食惡欲。三樹下坐。能破比丘為臥具惡欲。四身心寂靜。能破比丘為有惡欲。以是四藥除是四病。是名聖行。如是聖行則得名為少欲知足也。

Furthermore, the Nirvāṇa-sūtra states: "For renunciants, there are four kinds of foul sicknesses, because of which they cannot attain the four fruits of a śramaṇa. What are the four sicknesses? They refer to the four foul desires: first, the desire for robes; second, the desire for food; third, the desire for bedding; fourth, the desire for existence. There are four good medicines that can cure these sicknesses: first, robes made of rag patches can cure a bhikṣu's foul desire for robes; second, begging for food can shatter a bhikṣu's foul desire for food; third, sitting beneath a tree can shatter a bhikṣu's foul desire for bedding; fourth, tranquility of body and mind can shatter a bhikṣu's foul desire for existence. Removing these four sicknesses by means of these four medicines is called holy conduct. Such holy conduct can be called having few desires and being content."
