三因緣故，於天趣中，建立四眾者，一、依地邊際建立二眾，謂一四大王眾天居持雙山頂及須彌山頂等故；二、三十三天居須彌頂故，二欲界邊際建立魔眾，三語行邊際建立梵眾。

Because of three causes and conditions, four assemblies are established in the celestial realm: first, establishing two assemblies based on the boundary of the earth, namely the assembly of the devas of the Four Great Kings who dwell on the peaks of the Yugandhara mountains, the summit of Mount Sumeru, etc., and the Trāyastriṃśa devas who dwell on the summit of Mount Sumeru; second, establishing the assembly of Māra at the boundary of the desire realm; third, establishing the assembly of Brahmā at the boundary of verbal activities.
