Vaishravana
In Tibet, Vaiśravaṇa is known to be a worldly protector of the Dharma. He is also known as the King of the North. As guardian of the north, he is often shown on temple wall paintings outside the main door. He is also a god of wealth. Vaiśravaṇa is sometimes shown carrying a citron, the fruit of the jambhara tree. The fruit helps pick him out from depictions of Kuvera.
