第三心無厭倦者，景云：即用無足精進、慧、悲三法為體。五因緣內，一、自性有力；二、數貫習。由此二緣故無厭倦下，三出體：第三、精進；第四、妙慧；第五、悲心。故知三法為體。

Third, regarding indefatigability of mind, Jing says: it takes the three dharmas of insatiable vigor, wisdom, and compassion as its essence. Among the five causal conditions: 1. Inherent power in one's nature; 2. Frequent habituation. Because of these two conditions, one is indefatigable; below, three bring out the essence: 3. Vigor; 4. Wondrous wisdom; 5. Mind of compassion. Hence we know these three dharmas are its essence.
