首楞嚴義疏注經 10.382

10.382

二十五聖及妙吉祥雖各有說，功歸於佛，總名佛說。三種世間，故云一切器界所住境也。菩薩、二乘智正覺攝，餘皆有情世間。聖仙童子，此仙眾之一也。經中有此真言，大歡喜者，近得世間歡喜，遠得出世初地，由三義故歡喜：一能說人清淨；二所說法清淨；三所得果清淨。由斯義故皆大歡喜。

Although the twenty-five sages and Mañjuśrī each spoke, the merit belongs to the Buddha, so it is collectively termed "the Buddha spoke." "All" refers to the three realms of existence, meaning the environments in which the receptacle worlds abide. Bodhisattvas and the two vehicles are included in the realm of enlightened wisdom; the rest are all within the realm of sentient beings. "Holy ṛṣi youths" are one class among the gatherings of ṛṣis. As this true word is contained in the sūtra, "were filled with great joy" means that in the near term they obtained worldly joy, and in the long term they attained the supramundane first ground. They rejoiced on account of three reasons: first, the speaker is pure; second, the Dharma spoken is pure; third, the fruit obtained is pure. For these reasons, they were all filled with great joy.
