"Pulling out the arrow of hesitation" (The Erya states: "The you is the name of a beast; in shape it resembles a river deer, it is adept at climbing trees, and by nature it is full of doubts and suspicions. It constantly stays in the mountains, and if it suddenly hears a sound, fearing that someone is coming to harm it, it prematurely [yu] climbs a tree; after a long time when nothing happens, it descends, only to climb up again a moment later, repeating this many times. Therefore, one who is indecisive and full of suspicions is called 'youyu' [hesitant]. Alternatively, some say: 'In the custom of Longxi at that time, a puppy was called you. A dog follows someone walking, liking to run ahead beforehand [yu]; before the traveler arrives, it turns back to welcome and greet him. Hence, when the mind is undecided, it is called youyu.' Now, considering the treatises, hesitation is precisely doubt, which is subsumed under the afflictions; and because one cannot advance in wholesome qualities, this [arrow] must be pulled out).
