In the Padma Purana,
The lord of the earth, leaving the ocean, reached the eight-peaked Kailasa mountain, adorned with Jina temples, after a long time. || 72 ||
There, the Mandakini river, with its clear waters, was adorned with golden lotus pollen, the queen of the lord of the Sindhu. || 73 ||
Having stationed his army nearby, he engaged in delightful pastimes in the caves of Kailasa. || 74 ||
The celestial beings, then the earth-dwellers, in turn, relieved their weariness in the clear, comfortable, crystal-like waters of the Mandakini. || 75 ||
The horses, having their dust removed by the new leaves of the Meru tree, and having been given water, stood in humility, having been bathed. || 76 ||
The elephants, their bodies wet with water spray, having accumulated thick dust, and having had their great weariness removed by the river, were bathed for a long time by their keepers. || 77 ||
Remembering the story of the young girl, Ravana bowed respectfully to all the Jina temples and performed actions in accordance with Dharma. || 78 ||
Then, Indra had appointed Nalakubara as the guardian of the city called Durlagha, and when he learned from his spies that Ravana, with his army like a sea, was approaching with the desire to conquer, he, with a fearful mind, wrote a letter with all the news and sent it to Indra by a swift celestial being. || 79-81 ||
When Indra was going to the Meru mountain to worship the Jina images, the letter-carrier celestial being, bowing, placed Nalakubara's letter before him. || 82 ||
Having read the letter and understanding its meaning completely, Indra, by means of a letter, commanded, "You must remain here with great effort. You are the holder of the infallible weapon, until I return after worshipping the Jinas in the Panduka forest." || 83-84 ||
