太子瑞應本起經 2.25

2.25

「佛止樹下第二天，帝釋夜復來下聽佛說經。帝釋光影，甚益大明。迦葉夜起占候，見佛邊火光倍於昨四火明，心念：『是大沙門續事火也。』明旦復行問：『大道人得無事火？』佛言：『不也。昨天帝釋來下聽經，是其光耳。』迦葉念言：『是大沙門乃神聖。雖然，未及於道，不如我得羅漢也！』

"On the second day the Buddha stayed beneath the tree, Śakra came down again at night to hear the Buddha preach the scripture. Śakra's radiance and aura were even vastly brighter. Kāśyapa arose at night to observe the signs, and saw by the Buddha's side a fiery light twice as bright as the four fires of the night before. He thought to himself: 'This great śramaṇa must also be performing fire sacrifices.' The next morning he went again and asked: 'Is the Great Man of the Way perhaps performing fire sacrifices?' The Buddha said: 'No. Yesterday Śakra came down to hear the scripture; it was merely his light.' Kāśyapa thought: 'This great śramaṇa is indeed spiritually wondrous. Even so, he has not attained the Way, and is not equal to me, who have attained the status of an arhat!'
