首楞嚴義疏注經 3.127

3.127

「阿難！若復此味生於汝舌，在汝口中秖有一舌，其舌爾時已成酥味，遇黑石蜜應不推移，若不變移不名知味，若變移者舌非多體，云何多味一舌之知？」

"Ānanda! If this flavor were born from your tongue, in your mouth there is only one tongue; if that tongue had at that time already become the flavor of butter, when encountering dark cane-sugar it should not shift. If it does not shift, it cannot be called knowing flavor; if it shifts, the tongue is not multiple in substance, so how could multiple flavors be known by a single tongue?"
