The Middle Way in practical life
There is a large body of texts of discourses of the Buddha touching on lay life issues. Below, I paste a (probably not exhaustive) list of suttas compiled by a user from dhammalwheel forum. There's also an upcoming book from Bhikkhu Bodhi presenting a collection of suttas of discourses of the Buddha dealing with lay life themes: The Buddha's Teachings on Social and Communal Harmony: An Anthology of Discourses from the Pali Canon.
