經律異相 3.44

3.44

須彌山南有一大樹。高四千里。諸鉢叉鳥恒栖其上。樹常不動。有一小鳥。形類鶉鴳。住止其上。樹輒震撫。鉢叉問樹神言。汝無知。我身重大而自不動。小鳥來時反更震搖。神言。此鳥雖小。從海底食一金剛。金剛為物。所墮之處無不破散。所以大怖不能自安耳（出十卷譬喻經第七卷）。

South of Mount Sumeru there is a great tree four thousand li high. The pakṣa birds constantly roost upon it, and the tree is always motionless. There was a small bird, shaped like a quail, which came to stay upon it, and the tree immediately shook and trembled. The pakṣa asked the tree deity: “You have no sense! My body is heavy and large, yet you are naturally motionless; but when a small bird comes, you shake and tremble instead?” The deity said: “Although this bird is small, it has eaten an adamantine stone from the ocean bottom. As for the adamantine stone, wherever it falls, nothing fails to be shattered and scattered. Therefore, I am greatly terrified and cannot rest secure” (from the seventh fascicle of the *Ten Fascicle Parables Sūtra*).
