Vaishravana (Skt. Vaiśravaṇa; Tib. རྣམ་ཐོས་སྲས་, Namtösé, Wyl. rnam thos sras; Eng. 'Son of Viśravas') — one of the Four Great Kings, also known as Kubera. He is Guardian King of the North, in a realm called Adakavati (Tib. ལྕང་ལོ་ཅན, Canglocan, Wyl. lcang lo can), and leader of the yakshas (who are also called guhyakas).
Because his breath is harmful he keeps his mouth tightly closed. He confers spiritual and material wealth on practitioners of the Dharma, symbolized by the jewel-producing mongoose in his left hand.
