11.27

「頌曰至以立洲號」者，此即第五明黑山等。香醉山，謂此山中有諸香氣，嗅令人醉，故名香醉。一殑伽河，從東面出繞池一匝入東海。二信度河，從南面出繞池一匝入南海。三徙多河，從北面出繞池一匝入北海，即是此方盟津河也。四縛芻河，從西面出繞池一匝入西海。

"The verse says […] names the continents": this is the fifth, explaining the Black Mountains and so forth. Gandhamādana Mountain means that there are various fragrances in this mountain, smelling which makes people intoxicated, hence it is called Gandhamādana ('Intoxicating Fragrance'). First, the Gaṅgā River emerges from the east side, circles the lake once, and enters the eastern sea. Second, the Sindhu River emerges from the south side, circles the lake once, and enters the southern sea. Third, the Sītā River emerges from the north side, circles the lake once, and enters the northern sea; this is the Mengjin River of this land. Fourth, the Vakṣu River emerges from the west side, circles the lake once, and enters the western sea.
