"Then Anathapindika the householder, surrounded by about 500 lay followers, went to the Blessed One and, on arrival, having bowed down to him, sat to one side. As he was sitting there the Blessed One said to him, "Householder, you have provided the community of monks with robes, alms food, lodgings, & medicinal requisites for the sick, but you shouldn't rest content with the thought, 'We have provided the community of monks with robes, alms food, lodgings, & medicinal requisites for the sick.' So you should train yourself, 'Let's periodically enter & remain in seclusion & rapture.' That's how you should train yourself."" -AN 5.176
"Until recently (even up to the late 20th century), there is a common wrong view that spiritual training, especially mental cultivation or meditation, is only the domain of the monastic. The laity merely makes merit by serving and supporting the monastics. However, it is clear from the Pīti Sutta here that spiritual development by way of mental cultivation is just as important for the laity." - Piya Tan - pdf link
