大方便佛報恩經 3.16

3.16

爾時如來出于三昧。釋提桓因、忉利天王即以天衣敷師子座。爾時如來即昇此座，結加趺坐，如須彌山王處于大海。

At that time, the Tathāgata arose from samādhi. Śakra Devānām Indra, the king of Trāyastriṃśa Heaven, immediately spread celestial garments upon a lion seat. The Tathāgata then ascended this seat and sat cross-legged, like Mount Sumeru, king of mountains, situated in the midst of the great ocean.
