2.31

【那伽】此云龍。《別行疏》云：「龍有四種：一守天宮殿，持令不落。人間屋上，作龍像之爾。二興雲致雨，益人間者。三地龍，決江開瀆。四伏藏，守轉輪王大福人藏也。龍有四生，《俱舍》云：『卵生金翅鳥，能食四生龍。』《罵意經》云：『墮龍中有四因緣：一多布施，二嗔恚，三輕㑥（以豉）人，四自貢高。』《華嚴》云：『龍王降雨，不從身出，不從心出，無有積集，而非不見。但以龍王心念力故，霈然洪霔，周遍天下。如是境界，不可思議。』」

[Nāga] Translated here as dragon. The *Biexing shu* says: 'There are four kinds of dragons: first, those that guard heavenly palaces, holding them up so they do not fall—images of dragons are made on human roofs to represent this; second, those that raise clouds and bring rain, benefiting humankind; third, earth dragons, which dredge rivers and open canals; fourth, hidden treasures, which guard the treasures of wheel-turning kings and persons of great merit. Dragons have four modes of birth. The *Abhidharmakośa* states: "Egg-born garuḍas can eat dragons of all four births." The *Mayi jing* states: "There are four causes and conditions for falling into the realm of dragons: first, giving much; second, anger; third, treating people with contempt; fourth, arrogance." The *Avataṃsaka Sūtra* states: "When a dragon king brings down rain, it does not come from his body, nor does it come from his mind; there is no accumulation of it, yet it is not unseen. Merely through the power of the dragon king's mental intention, torrential rain pours down, covering all beneath heaven. Such a realm is inconceivable."'
