28.26

「無太過失至有惡靜慮」者，答。無太過失，要與善靜慮相似義中方名染靜慮，餘非相似不名靜慮。生芽名種、敗種名種，似生種故立以種名。等謂等取涸池、死人等，此即引喻。世尊亦說有惡靜慮，即味靜慮。此即引證。

As for "There is no fault of being overly broad... there are bad dhyānas": this is the answer. There is no fault of being overly broad: it is only when there is similarity in meaning to wholesome dhyāna that it is called defiled dhyāna, whereas anything else that lacks similarity is not called dhyāna. A seed that sprouts is called a seed, and a ruined seed is also called a seed; because it resembles a viable seed, it is given the name 'seed'. 'And so forth' includes dried ponds, dead men, and the like; this adduces an analogy. The World-Honoured One also spoke of 'bad dhyānas', which refers to relish-associated dhyāna (āsvādanā-dhyāna). This adduces proof.
