[998] Therein, which are the six explorations of joy (somanassupavicārā)?
Having seen a form (rūpa) with the eye, one explores a form that is a basis for joy; having heard a sound with the ear …; having smelled an odour with the nose …; having tasted a flavour with the tongue …; having touched a tangible object (phoṭṭhabba) with the body …; having cognized a mental phenomenon (dhamma) with the mind (mano), one explores a mental phenomenon that is a basis for joy. These are the six explorations of joy.
