Itivuttaka 101

This was said by the Blessed One, said by the Arahant, so I have heard: “Monks, these four things are next to nothing, both easy to gain & blameless. Which four? Cast-off cloth is next to nothing, both easy to gain & blameless. Alms food is next to nothing, both easy to gain & blameless. The root of a tree as a dwelling place is next to nothing, both easy to gain & blameless. Medicine made of smelly urine1 is next to nothing, both easy to gain & blameless. These are the four things that are next to nothing, both easy to gain & blameless. When a monk is content with what is next to nothing, easy to gain & blameless, then I say that he has one of the component factors of the contemplative life.”
