法苑珠林 33.56

33.56

又十誦律云。洗浴得五利。一除塵垢。二治身皮膚令一色。三破寒熱。四下風氣調。五少病痛。舍利弗。夏盛熱時有一客作人。園中汲水灌樹。見舍利弗發小信心。喚舍利弗脫衣樹下。以水澆洗身得輕涼。作人後命終即生忉利天上。有大威力。為功雖少。以遇良田獲報甚多。即下詣舍利弗所散華供養。舍利弗因其信心為說法要。得須陀洹果。

Furthermore, the Daśādhyāya-vinaya says: Bathing yields five benefits: first, removing dust and dirt; second, curing the skin of the body to make it of a single color; third, dispelling cold and heat; fourth, regulating downward-moving flatus; fifth, reducing illness and pain. Śāriputra: During the height of the summer heat, there was a hired laborer drawing water in an orchard to irrigate the trees. Seeing Śāriputra, he gave rise to a small measure of faith, called to Śāriputra to take off his robes under a tree, and poured water to wash him so that his body became light and cool. After the laborer's life ended, he was immediately born in Trāyastriṃśa Heaven with great majesty and power. Although his merit was small, because he encountered an excellent field [of merit], he received a very great retribution. He immediately descended to Śāriputra's dwelling, scattering flowers in offering. Because of his faith, Śāriputra expounded the essentials of the Dharma for him, and he attained the fruit of stream-entry.
