Visuddhimagga XIV-98

Somanassupekkhāyogato pana dvipañcaṭṭhānabhedato ca tassā bhedo.

因为与喜、舍相应，及有二处、五处（作用）的差别之故，所以它有二种各别；

Ñ(XIV,98): But it is classed according to its association with joy or with equanimity, and according to its being divisible into that with two positions and that with five positions [in the cognitive series].

Etāsu hi ekā ekantamiṭṭhārammaṇe pavattisabbhāvato somanassasampayuttā hutvā santīraṇatadārammaṇavasena pañcadvāre ceva javanāvasāne ca pavattanato dviṭṭhānā hoti.

即于此等（二者）之中，一（40），是因为专于好的所缘而转起为自性之故，所以成为喜相应的，并且因为是由于推度及彼所缘（的二作用）于（眼等的）五门的速行的末后而转起之故，所以有二处（作用）。

Ñ: For of these, (40) one is associated-with-joy because of its presence when entirely desirable objects occur, and it has two positions [in the cognitive series] because it occurs as investigating at the five doors and as registration at the end of impulsion.

Ekā iṭṭhamajjhattārammaṇe pavattisabbhāvato upekkhāsampayuttā hutvā santīraṇatadārammaṇapaṭisandhibhavaṅgacutivasena pavattanato pañcaṭṭhānā hoti.

一（41），是因为于好的中所缘（舍）而转起为自性之故，所以成为舍相应的，并且因为是由于推度、彼所缘、结生、有分及死而转起之故，所以有五处（的作用）。

Ñ: (41) The other kind is associated-with-equanimity because of its presence when desirable-neutral objects occur, and it has five positions since it occurs as investigation, registration, rebirth-linking, life-continuum, and death.
