Angkor Wat (Angkor Monastery, Angkor Junior) is a mausoleum temple built by Sulliyah Bama II for himself. He believes that he and Vishnu will become one after his death. It is also the only monastery in Angkor with its main entrance facing west. The original name of Angkor Wat is Vrah Vishnulok, which means "the Temple of Vishnu". In the previous article, we mentioned "Vishnulok", which is one of the three main Hindu gods, representing "maintenance". In the late 12th century, Angkor Monastery gradually transformed, showing the characteristics of many Buddhist temples. Hindu monasteries generally face east, but probably because the eastern part is relatively narrow, there is no large-scale venue for activities, so they change to the west.
