Visuddhimagga VIII-31

Byādhipi ‘‘imināva byādhinā sattā maranti, nāññenā’’ti vavatthānābhāvato animitto.

（2）「病」──「有情必以此病而死，不以他病」，实不能如是确定，故为无相。

Ñ(VIII,31): And the sickness has no sign because there is no definition such as: Beings die only of this sickness, not of any other.

Cakkhurogenāpi hi sattā maranti, sotarogādīnaṃ aññatarenāpi.

因为有情以眼病可死，以耳病等任何病亦可死的。

Ñ: For beings die of eye disease or of any one among those beginning with ear disease (see A.v, 110).
