Go-rams-pa bSod-nams-seng-ge was one of the brilliant Tibetan scholars of the fifteenth century. His works on Buddhist philosophy and tantras have attained the status of authority within the Sa-skya-pa tradition. The sDom gsum kha skong, is one of the most important works of this scholar, summarizing his understanding of the entire spectrum of Buddhist teaching, in five related chapters. It can be profitably read as a record of intellectual activities among Tibetan Buddhist authors of that time.
