Tosu Gisei

The forty-fourth patriarch was Priest T'ou-tzu. He studied with [Fushan] Yuan-chien. Yuan-chien had him inspect the [story of the] nonbuddhist asking the Buddha, "Aside from speech, aside from silence. " After three years, one day [Yuan-chien] asked him, "Do, you remember the case? Try to present it." The master was about to speak when Yuan-chien put his hand over his mouth. The master was thoroughly enlightened.
