The Phra Ubosot at Wat Pho contains the main Buddha statue, called Phra Tang Pha Thip. It is in meditation posture in Ayutthaya style. The murals on the wall of Phra Ubosot feature all levels of heaven. The eight pearl-inlaid doors feature the Ramayana epic. The chapel boundary wall is decorated with bas-reliefs from the Ramayana. When walking around Bangkok, you will see often images on transparent paper for sale. These were originally copied (not anymore) from the outer wall of the chapel.
Wat Pho has long been involved in health. Different statues of hermits in exercise postures can be seen. At present Wat Pho is still a center for traditional Thai massage, which can be experienced in situ. The many inscriptions at Wat Pho indicate that the temple was a major institute of education and is considered the first 'open university' in Thailand.
