維摩經略疏 3.53

3.53

"When among princes, he was honored among princes, showing them loyalty and filial piety": Vimalakīrti manifested clarity, understanding, filial piety, and respect in his trace; therefore he was honored by them. As for princes: being sons and subjects, as sons they must be filial, and as subjects they must be loyal. According with the four capacities and employing the four teachings, he preached for them the four ways of sincerity and filial piety, making them the sons of the four kinds of Dharma Kings. Following the practice of the four teachings is called filial piety; not begrudging body and life to propagate the four teachings is called loyalty, leading all sentient beings to enter the four lands.
