瑜伽論記 11.73

11.73

泰云：壞法壞時苦者，可壞時生苦也。盡法盡時苦者，可盡之法若至盡時便生大苦，前但壞不盡也。八法中，不言苦，但言利等三者，即此內明苦故，不言苦也。

Tai says: the suffering when disintegrating phenomena disintegrate means that suffering arises when they are disintegrating. The suffering when exhausted phenomena are exhausted means that when exhaustible phenomena reach the point of exhaustion, great suffering arises; the former is merely disintegration without exhaustion. In the eight phenomena, it does not state 'suffering', but mentions only three such as gain and so forth, because suffering is explained within this context, so it does not mention 'suffering'.
