Visuddhimagga VI-42

Purisassa pana itthisarīraṃ itthiyā vā purisasarīraṃ na vaṭṭati.

男子对于女体（尸），女子对于男体（尸）是不适宜的。

Ñ(VI,42): However, a female body is not appropriate for a man or a male one for a woman;

Visabhāge sarīre ārammaṇaṃ na upaṭṭhāti, vipphandanasseva paccayo hoti.

在异性的尸体不能生起（不净相的所缘），只是扰乱的缘而已。

Ñ: for the object, [namely, the repulsive aspect], does not make its appearance in a body of the opposite sex, which merely becomes a condition for the wrong kind of excitement [(vipphandana)].

‘‘Ugghāṭitāpi hi itthī purisassa cittaṃ pariyādāya tiṭṭhatī’’ti (a. ni. 5.55) majjhimaṭṭhakathāyaṃ vuttaṃ.

如中部义疏中说：「虽系腐烂的女人亦能夺去男子的心」。

Ñ: To quote the Majjjhima Commentary: 'Even when decaying [(Ugghāṭita)] a woman invades a man's mind and stays there'.

Tasmā sabhāgasarīreyeva evaṃ chabbidhena nimittaṃ gaṇhitabbaṃ.

所以当对同性的尸体以此六法取相。

Ñ: That is why the sign should be apprehended in the six ways only in a body of the same sex.
