首楞嚴義疏注經 1.112

1.112

"Kāśyapa: here translated as 'Light-Drinker clan'. In high antiquity their primal ancestor was a ṛṣi whose body possessed radiant light that eclipsed the glow of lamps. People all marvelled at him and called him the Light-Drinking Ṛṣi, and on this basis established the clan name. Because the Venerable One was foremost in the superior practice of dhūta, he is called 'Mahā' ('Great'). As for 'not impartial', Subhūti abandoned the poor to follow the rich, while Kāśyapa abandoned the rich to follow the poor; both were reproved by Vimalakīrti. Here mentioning the Tathāgata is with respect to his endorsement, attributing the merit to the Buddha. However, that the Buddha constantly begged for food without hindrance or discrimination was due to five reasons: first, because internally he realized the principle of equality, externally seeing no mark of poverty or wealth; second, his mind was free from greed and arrogance, and his compassion benefited without partiality; third, to manifest majestic virtue, not fearing mad elephants, liquor shops, or courtesans' houses; fourth, to put an end to the suspicions and jealousies of ordinary people; fifth, to shatter the discriminations of the two vehicles. Therefore [Ānanda] could look up to and emulate him, practicing impartiality. 'Saving them from doubts and slanders' refers to putting an end to the suspicions and jealousies of ordinary people.
