注維摩詰經 7.144

7.144

什曰：一心，梵本云「和合」。道品心中有三相，一發動、二攝心、三名捨。若發動過則心散，散則攝之。攝之過則沒，沒則精進令心發動。若動靜得適，則任之令進，容豫處中是名為捨。捨即調御，調御即和合也。譬如善御，遲則策之、疾則制之，舒疾得宜則放之令去，縱步夷塗必之所往也。生曰：一心謂捨也。若無復高下遲疾，便宜任之，以一心矣。

[Kumāra]jīva says: 'One-pointed mind'—the Sanskrit text says 'harmony' (*saṅgata* / *samāhita*). Within the mind of the path-factors there are three aspects: first, arousal; second, collecting the mind; third, equanimity. If arousal is excessive, the mind becomes distracted; when distracted, one collects it. If collecting it is excessive, it sinks; when it sinks, one exerts vigor to arouse the mind. If activity and stillness are properly balanced, one leaves it to proceed; being relaxed and dwelling in the middle is called equanimity. Equanimity is guiding; guiding is harmony. For example, like a skilled charioteer: when slow, he whips them; when too fast, he reins them in; when slow and fast are appropriate, he lets them go, and stepping freely on a level road, they will surely reach where they are going.
[Dao]sheng says: 'One-pointed mind' refers to equanimity. When there is no longer high or low, slow or fast, it is appropriate to give free rein to it, using a unified mind.
