Thao Wessuwan or Vaiśravaṇa (वैश्रवण) is a very well known image amongst Thai Buddhists and has become a popular amulet of late, most commonly worn as protection from evil spirits and to attract financial gain. Thao Wessuwan is the leader of all ghosts and demons and large statues of him can be seen in front of the gates of many temples across Thailand and a huge one also oversees the departures area in Suvarnabhumi airport, Bangkok.
