Srimad Bhagavatam Canto 08, Chapter 10, Text 25

SB 8.10.25

airavatam dik-karinam
 arudhah susubhe sva-rat
yatha sravat-prasravanam
 udayadrim ahar-patih
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Sitting on Airavata, an elephant who can go anywhere and who holds water and wine in reserve for showering, Lord Indra looked just like the sun rising from Udayagiri, where there are reservoirs of water.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
On the top of the mountain called Udayagiri are large lakes from which water continuously pours in waterfalls. Similarly, Indra’s carrier, Airavata, holds water and wine in reserve and showers it in the direction of Lord Indra. Thus Indra, King of heaven, sitting on the back of Airavata, appeared like the brilliant sun rising above Udayagiri.
