Mbh 3.42.4b

And in that region there was no sun or moon or fire to give light, but it blazed in light of its own, generated by virtue of ascetic merit. And those brilliant regions that are seen from the earth in the form of stars, like lamps (in the sky)--so small in consequence of their distance, though very large--were beheld by the son of Pandu, stationed in their respective places, full of beauty and effulgence and blazing with splendour all their own. And there he beheld royal sages crowned with ascetic success, and heroes who had yielded up their lives in battle, and those that had acquired heaven by their ascetic austerities, by hundreds upon hundreds. And there were also Gandharvas, of bodies blazing like the sun, by thousands upon thousands, as also Guhyakas and Rishis and numerous tribes of Apsaras. And beholding those self-effulgent regions, Phalguna became filled with wonder, and made enquiries of Matali. And Matali also gladly replied unto him, saying, ‘These, O son of Pritha, are virtuous persons stationed in their respective places. It is these whom thou hast seen, O exalted one, as stars, from the earth.’ Then Arjuna saw standing at the gates (Indra’s region) the handsome and ever victorious elephant--Airavata--furnished with four tusks, and resembling the mountain of Kailasa with its summits. And coursing along that path of the Siddhas, that foremost of the Kurus and the son of Pandu, sat in beauty like Mandhata--that best of kings. Endued with eyes like lotus leaves, he passed through the region set apart for virtuous kings. And the celebrated Arjuna having thus passed through successive regions of heaven at last beheld Amaravati, the city of Indra.”
