成唯識論演祕 1.139

1.139

問：《瑜伽論》云，住滅定時，此勝義苦暫時寂靜，故名為樂。當入定時唯滅無漏心、心所法，豈無漏法名勝義苦？

Question: The *Yogācārabhūmi* says that when dwelling in the attainment of cessation, this suffering of the ultimate truth is temporarily pacified, and therefore it is called pleasure. When one enters this concentration, only uncontaminated minds and mental factors are ceased; how could uncontaminated phenomena be called the suffering of the ultimate truth?
