3.133

問曰：上所明三止，若係緣、制心，此二止並是事止，應但發事中禪定，唯體真一止，既是理止，應發理中禪定，今何故三止通皆發事理諸禪？此則因果渾而無別。

Question: Regarding the three cessations explained above, fixing on conditions and reining in the mind are both phenomenal cessations, so they should only give rise to dhyāna absorptions within phenomena; only the single cessation of embodying truth is a cessation of principle, so it should give rise to dhyāna absorptions within principle. Why is it that now all three cessations commonly give rise to all dhyānas of phenomena and principle? If so, cause and effect are confounded without distinction.
