Prasat Bayon and the face of Jayavarman VII
Wrongly many people believe that the face reliefs are faces of Lord Buddha but they are the faces of a Boddhisattva, an enlightened (bodhi) existence (sattva) or an enlightenment-being. Its believed that there are the faces of king Jayavarman VII.
The similarity of the 216 gigantic faces on the temple's towers to other statues of the king has led many scholars to the conclusion that the faces are representations of King Jayavarman VII himself.
From the vantage point of the temple's the upper terrace, however, one is struck by "the serenity of the stone faces" occupying the many towers.
