修習止觀坐禪法要 1.81

1.81

此三事，的無前後，隨不調者而調適之，令一坐之中，身息及心三事調適，無相乖越，和融不二。此則能除宿患，妨障不生，定道可剋。

These three things have no fixed sequence; one harmonizes whichever is unharmonized, causing the three things—body, breath, and mind—to be tempered and balanced throughout a single sitting, not conflicting with or exceeding one another, blending harmoniously as non-dual. This can eradicate chronic ailments, prevent obstacles and hindrances from arising, and allow the path of concentration to be attained.
