4.255

宋赦書一件應天下。舊來有名德僧為眾師法未曾諡名者。仰所屬勘會聞奏。諡給師號。詔天下軍州創崇寧寺。又改額曰天寧寺。至高宗改報恩寺光孝。追崇嚴薦（南渡中興小曆）。

An imperial edict of the Song stated: Throughout the empire, whenever there has previously been an eminent monk of virtuous reputation who served as a model for the multitude but has never received a posthumous title, the local authorities are instructed to investigate, verify, and memorialize the throne to bestow a master's title upon him. An imperial decree also ordered all commanderies and prefectures across the empire to establish Chongning Monasteries, which were later renamed Tianning Monasteries. Down to Emperor Gaozong, they were changed to Bao'en Monasteries and Guangxiao Monasteries, in order to pay posthumous honor and reverent memorial (Brief History of the Southern Crossing and Restoration).
