The key to flow/meditativr-state is sussposed to be fitting the processing capability someone's brain has , to the task. That way all of your attention is given to a network called "task mode network" and no attention is left to the "default mode network " (which is resonsible for mental chatter and self in past/present) so the brain becomes quiet.
So maybe there's a way to make chores more demanding of attention[1] ? Like deciding to do them in a different way or focus on more/different details ? Maybe that's why the Japanese tea ceremony is so complicated ?
