[435] And what, bhikkhus, are the eighteen feelings (vedanā)? The six mental explorations (upavicāra) accompanied by joy (somanassa), the six mental explorations accompanied by grief (domanassa), the six mental explorations accompanied by equanimity. These, bhikkhus, are called the eighteen feelings.
