Ring brgyud bkav ma went through the early, intermediate and late development stages and became a sect boasting long history and orthodox dharma lineage in Tibet. The *sutras* such as sgyu vphrul, vdus pa mdo and sems phyogs expounded the doctrine of Ring brgyud bkav ma. It is worth mentioning that gnyags dzanya na ku ma ra (the 8th century CE) in the early stage, gnubs sangs rgyas ye shes (772～867 CE) in the intermediate stage and zur gsum in the late stage all made a great contribution to promoting the development of Ring Brgyud bkav ma.
