大唐西域記 8.58

8.58

長者獻[麩-夫+少]側有窣堵波，四天奉鉢處。商主既獻[麩-夫+少]蜜，世尊思以何器受之。時四天從四方來，各持金鉢，而以奉上。世尊默然，而不納受，以為出家不宜此器。四天王捨金鉢，奉銀鉢，乃至頗胝、琉璃、馬腦、車渠、真珠等鉢，世尊如是皆不為受。四天王各還宮，奉持石鉢，紺青映徹，重以進獻。世尊斷彼此故，而總受之，次第重疊，按為一鉢，故其外則有四隆焉。

By the side of the merchant-offering place is a stûpa. This is the spot where the four Deva-rajas presented (Buddha) with a pâtra. The merchant-princes having made their offering of wheat-flour and honey, the Lord thought with himself in what vessel he should receive it. Then the four Deva-rajas coming from the four quarters, each brought a golden dish and offered it. The Lord sat silently and accepted not the offerings, on the ground that such a costly dish became not the character of a hermit. The four kings casting away the golden dishes, offered silver ones; afterwards they offered vessels of crystal (po-ch'i), lapis-lazuli (liu-li), cornelian (ma-nao), amber (ku-ch'i), ruby (chin chu), and so on. The Lord of the World would accept neither of them. The four kings then returned to their palaces and brought as an offering stone patras, of a deep blue colour and translucent. Again presenting these, the Lord, to avoid accepting one and rejecting the others, forthwith joined them all in one and accepted them thus. Putting them one within the other, he made one vessel of the four. Therefore may be seen the four borders on the outside of the rim (of the dish).
