首楞嚴義疏注經 4.324

4.324

「本狂自然，本有狂怖，未狂之際狂何所潛？不狂自然，頭本無妄，何為狂走？」

"If the original madness was spontaneous, fundamentally possessing mad fear, then before he was mad, where was the madness concealed? If the non-madness was spontaneous, and the head fundamentally had no falsehood, why did he run about madly?"
