"In Rajasthan, the Sri Alvar Tirth of the Jains celebrates the power of Mandodari’s chastity: Ravana, the king of Lanka observed the vow of taking meals only after worshipping God. Once he was going in a plane [sic] to a foreign country. When it was time for lunch, he landed near Alvar to take rest. He remembered the vow of worshipping God but he had forgotten to bring the idol with him. In order to keep the vow, Mandodari made an idol of sand and invested it with life by reciting the mantra of Namaskar. Having worshipped God with devotion, Ravan and Mandodari kept their vow. By virtue of the vow and Mandodari’s chastity, the presiding deity made the idol adamantine. Thus, the idol of Parshvanathji worshipped by Mandodari and Ravan began to be known as ‘Shri Ravan Parshvanath’."
