仁王經疏 1.225

1.225

釋曰：第三、勸發三慧。言諦聽者，發生聞慧，因聞生故。善恩念之者，發生思慧，因思生故。如法修行者，顯其修慧，因修禪定所生慧故。

Commentary: Third, encouraging the generation of the three wisdoms. The words "listen attentively" generate the wisdom arising from hearing, because it is generated due to hearing. "Think upon it well" generates the wisdom arising from reflection, because it is generated due to reflection. "Practice according to the Dharma" reveals the wisdom arising from cultivation, because it is the wisdom generated due to cultivating meditative concentration.
