蠅子投窗
唐 古靈神贊禪師（生卒年不詳）

空門不肯出，投窗也太痴；
千年鑽故紙，何日出頭時。

──《全唐詩》

Housefly Banging Against the Window
Guling Shenzan (Years unknown, Tang Dynasty)
English translation: John Balcom

Unwilling to leave through the empty door,
Banging against the window is too ignorant.
For a thousand years, studying these ancient pages,
When will you achieve the Way?
