維摩經疏卷第三．第六 3.20

3.20

當了已下第二明其說法之德。翻前四失以明四德。當了根者。第一彰說法人知根之德。明了眾生根利鈍故。善於知見者。二明證法之德。證深法故無所罣礙。大悲心者第三明大悲之德。善為眾生演大乘故。大乘之法拔苦盡原。所以成悲也。報佛恩者。四明報恩之德。善教眾生發菩薩心自致成佛。成佛即有法。有法即化眾生。是其僧寶展轉相教。故名三寶不段即報佛恩也。

'One should understand...' and so on: the second part clarifies the virtues of expounding the Dharma, turning around the previous four faults to clarify the four virtues. 'One should understand the faculties': the first reveals the speaker's virtue of knowing faculties, clearly understanding whether the faculties of sentient beings are sharp or dull. 'Skilled in knowledge and vision': the second clarifies the virtue of realizing the Dharma, because in realizing the profound Dharma there are no hindrances. 'Great compassionate mind': the third clarifies the virtue of great compassion, being skilled at expounding the Mahāyāna for sentient beings. Because the Dharma of the Mahāyāna uproots suffering to its ultimate source, compassion is accomplished. 'Repaying the Buddha's kindness': the fourth clarifies the virtue of repaying kindness, being skilled at teaching sentient beings to generate the bodhisattva mind and themselves attain buddhahood. When buddhahood is attained, there is the Dharma; when there is the Dharma, sentient beings are transformed, which is the Jewel of the Saṅgha, teaching one another in turn; thus the Three Jewels do not cease, which is repaying the Buddha's kindness.
