mentioned here is Sajiwan Buddhist temple, located not far south from Prambanan, probably was built during the end of Rakai Kayuwangi (King Lokapala) reign and completed in Balitung's reign. The temple is dedicated to Nini Haji Rakryan Sanjiwana, linked to Sri Kahulunnan, another name of queen Pramodhawardhani. This temple probably was a mortuary temple dedicated as pedharmaan (dedication) for the deceased queen mother. The rivalry between Balitung and Daksha was probably a result of the previous contest of succession between Rakai Gurunwangi and Rakai Kayuwangi (King Lokapala)—both are descendants of Rakai Pikatan. During the rule of his brother-in-law—Balitung, Mpu Daksa held the position as Rakai Hino, according to Taji Gunung inscription (dated 21 December 910), that mentioned about the partition of Taji Gunung area between him and Rakai Gurunwangi. It seems that Rakai Gurunwangi allied himself with his nephew Daksha. Historian Boechari is certain that the reign of Balitung was ended as the result of Mpu Daksha's rebellion. According to Taji Gunung inscription (910) Daksha was still as Rakai Hino, while in the stele of Timbangan Wungkal (913) he already ascended to the throne as the king. Although the kingdom also enjoyed relative peace and prosperity, after King Balitung, it seems that the construction of grand temples are decreased in both quality and quantity. Daksha ruled over the centre and the east portions of Java. King Daksha (r. 910–919) and his successor King Tulodong (r. 919–924) also ruled from Poh Pitu. The next monarch, King Wawa (r. 924–929) returned the capital back from Poh Pitu to Mataram. The Sanggurah inscription (dated 2 August 928)—found in Malang area in East Java is particularly interesting, since it mentioned about the deed of Sri Maharaja Rakai Pangkaja Dyah Wawa Sri Wijayalokanamottungga (King Wawa) that granted the Sima status to the land in and around the source of Brantas river in present-day Batu and Malang area. This means that during the reign of Wawa, the kingdom has expanded eastward by establishing settlements (Sima lands) along the river Bengawan Solo and Brantas.
