9.26

（十七）　時有達禪師者。得水觀三昧。每入此定。有窺之者。唯見清水凝渟滿室。沙門道僊從達遊。得火光三昧。所居之室玄夜大明焉。

(17) At that time, there was a Chan Master Da who had attained the water-visualization samādhi. Whenever he entered this concentration, anyone who peeked in saw only clear water standing still and filling the entire room. The śramaṇa Daoxian studied with Da and attained the fire-light samādhi; the room in which he stayed shone brightly in the dead of night.
