摩訶止觀 8.126

8.126

一切眾生皆具此理而不能識，隨見思流，沒分段海。深生悲愍，欲與非有即空道滅之樂。是為有疾菩薩能以空觀調伏其心。心調伏故，實疾除愈。以慈悲故，權疾則生，生分段土，視分段人猶如一子。子既有病，父母亦病，因以身疾而慰喻之；子病若愈，父母亦愈。是名「體、析慰喻有疾菩薩」也。

All sentient beings possess this principle yet cannot recognize it; drifting along the flow of views and thoughts, they sink into the ocean of fragmented [birth and death]. A bodhisattva gives rise to deep compassion, wishing to bestow upon them the joy of the path and cessation—which are non-existent and identical with emptiness. This is an ill bodhisattva capable of subduing their own mind through the contemplation of emptiness. Because the mind is subdued, the actual illness is cured. Out of loving-kindness and compassion, an expedient illness then arises: being born into the realm of fragmented [birth and death], the bodhisattva regards people of fragmented [birth and death] as their only child. Since the child is ill, the parents are also ill; thus, by means of their own physical illness, they console and comfort them. If the child's illness is cured, the parents are also cured. This is called "consoling and comforting the ill bodhisattva by means of [the contemplation of] emptiness through embodiment or analysis."
