Returning to the marketplace - examples

In the Ten Ox Herding Pictures of Zen the final picture is commonly depicted as returning to the marketplace. Enlightenment is said to be doing the most ordinary things in a most extraordinary way. It is very different at many levels from the Theravada model of an Arhat who recollects past lives, walks through walls, flies in the air and so on. Though there are references to *vasanas* which prevent the Arhat from Buddha like perfection, they are not commonly what comes to mind when one thinks Arhat. It is reinforced by the belief that one who has such attainment will leave the family, never have romantic worldly ideas, become a monk and generally be holy, strictly confirming to popular ideas of what is holy - i.e separate from this undesirable world of samsara. The Zen model doesn't even have the label Arhat that makes such attainment separate and special. Zen masters are of course famous for doing silly things like playing with kids, drinking wine, teaching in whore houses and so on. I've read similar things in the Tibetan tradition. Though it's another matter that most Zen masters obsess with lineage, robes, proper form and such. I'm looking for sutras, books, biographies or examples and generally any text that deals with returning to the marketplace in various traditions. Any tradition is fine. Does the Theravada canon have such ideas anywhere at all? Perhaps Tibetan? Thanks.
