Mbh 2.9.1a

‘Narada said--O Yudhishthira, the celestial Sabha of Varuna is unparalleled in splendour. In dimensions it is similar to that of Yama. Its walls and arches are all of pure white. It hath been built by Viswakarma (the celestial architect) within the waters. It is surrounded on all sides by many celestial trees made of gems and jewels and yielding excellent fruits and flowers. And many plants with their weight of blossoms, blue and yellow, and black and darkish, and white and red, that stand there, or excellent bowers around. Within those bowers hundreds and thousands of birds of diverse species, beautiful and variegated, always pour forth their melodies. The atmosphere of that mansion is extremely delightful, neither cold nor hot. Owned by Varuna, that delightful assembly house of pure white consists of many rooms and is furnished with many seats. There sitteth Varuna attired in celestial robe, decked in celestial ornaments and jewels, with his queen, adorned with celestial scents and besmeared with paste of celestial fragrance. The Adityas wait upon and worship the illustrious Varuna, the lord of the waters. And Vasuki and Takshaka, and the Naga called Airavana; Krishna and Lohita; Padma and Chitra endued with great energy; the Nagas called Kamvala and Aswatara; and Dhritarashtra and Valahaka; Matimat and Kundadhara and Karkotaka and Dhananjaya; Panimat and the mighty Kundaka, O lord of the Earth; and Prahlada and Mushikada, and Janamejaya,--all having auspicious marks and mandalas and extended hoods;--these and many other snakes. O Yudhishthira, without anxiety of any kind, wait upon and worship the illustrious Varuna.
