Vaishravana

In Buddhism, Vaishravana is the guardian king (lokapala) of the north, one of the four guardian kings who are often found at the entrances to temples. Vaishravana is also sometimes worshiped as a wealth deity and at times as a martial deity. Depending on the emphasis, he is depicted as an armored warrior, often mounted on a lion, carrying a mongoose or holding a stupa/pagoda.
