The Sdok Kak Thom temple, located near the present day Thai town of Aranyaprathet, was also constructed during his reign. The temple was home to a gray sandstone stele, 1.51 meters high, with a detailed inscription that recounted the sequence of previous Khmer kings. The inscription stele is now part of the collection of the national museum in Bangkok.

During his reign, several attempted rebellions, in 1051 and 1065, were crushed by his general Sangrama.{{rp|138–139}}{{rp|104}}
