小乘之成實宗及經部，謖眾生唯有一識，一識依於六根而緣六境，而說明之以經中所說六窗一猿之喻。是亦有一理。密教亦立一識。中臺大日尊之法界體性智是也。
One sense or perception; the one individual intelligence or soul which uses the various senses, likened to a monkey which climbs in and out of the various windows of a house— a Satyasiddhi and Sautrāntika doctrine. Also, a Vairocana maṇḍala.
一一識 小乘成實宗及經部主張眾生唯具有一識，即總該一切一心識、阿賴耶識、末那識、意識等諸識而立一識。此一識藉六根來認識六境；並舉六窗一猿之譬喻加以說明。密教亦立一識，以之為中台大日尊之法界體性智。p139
