The Long Āgama Sūtra 14.20

14.20

時，世尊所止因陀羅窟，自然廣博，無所障碍。爾時，帝釋與忉利諸天及般遮翼皆禮佛足，於一面坐，帝釋白佛言：「一時，佛在舍衛國婆羅門舍，爾時世尊入火焰三昧，我時以少因緣，乘千輻寶車，詣毘樓勒天王所，於空中過，見一天女叉手在世尊前立，我尋語彼女言：『若世尊三昧起者，汝當稱我名字，問訊世尊：起居輕利，遊步強耶？』不審彼女後竟為我達此心不？世尊！寧能憶此事不？」

The Bhagavān then made the Indrasāla Cave enlarge itself so that none of them were obstructed by it. Lord Śakra, the Trāyastriṃśa gods, and Pañcaśikha all bowed at the Buddha’s feet and sat to one side.

Lord Śakra said to the Buddha, “One time, the Buddha was staying at a priest’s residence in Śrāvastī. At the time, the Bhagavān had entered the samādhi of blazing fire. For some reason, I was riding my thousand-spoked treasure chariot to visit Virūḍhaka. As I went by in the sky, I saw a goddess standing with her palms together in front of the Bhagavān. I immediately said to that goddess, ‘If the Bhagavān rouses from samādhi, you should exchange these greetings with the Bhagavān in my name: “Has your daily life been easy? Are you in good health?”’ I wondered later if she had conveyed this thought for me. Bhagavān, do you recall if she did?”
