Equanimity and the sense doors

MN 137 Salayatanavibhanga Sutta - The Exposition of the Sixfold Base

4. “Herein, what are the six kinds of equanimity based on the household life? On seeing a form with the eye, equanimity arises in a foolish infatuated ordinary person, in an untaught ordinary person who has not conquered his limitations or conquered the results [of action] and who is blind to danger. Such equanimity as this does not transcend the form; that is why it is called equanimity based on the household life.
“On hearing a sound with the ear…On smelling an odor with the nose…On tasting a flavor with the tongue…On touching a tangible with the body…On cognizing a mind-object with the mind, equanimity arises in a foolish infatuated ordinary person, in an untaught ordinary person who has not conquered his limitations or conquered the results [of action] and who is blind to danger. Such equanimity as this does not transcend the mind-object; that is why it is called equanimity based on the household life. These are the six kinds of equanimity based on the household life.
