The Great Perfection doctrine does not seem to be directly derived from any of the Indian philosophical schools; its precise connections to the Indian Buddhist tradition have yet to be established. Some scholars (Evans- Wentz being perhaps the first) have claimed an historical link and doctrinal affinity between the Great Perfection and the Chan or Zen traditions of China and Japan, but the precise relationship between the two remains to be fully investigated. It is noteworthy that certain of the earliest extant Great Perfection texts specifically contrast their own tradition with that of Chan.
