the Land of Tibet, Mipham Rinpoche described the four main schools as follows: There is another minor sect, the Bodong school. This tradition was founded in 1049 by the Kadam teacher Mudra Chenpo, who also established the Bodong E Monastery. Its most famous teacher was Bodong Penchen Lénam Gyelchok (1376–1451) who authored over one hundred and thirty-five volumes. This tradition is also known for maintaining a female tulku lineage of incarnated lamas called the Samding Dorje Phagmo. While Yungdrung Bon considers itself a separate religion with pre-Buddhist origins, and it is considered as non-Buddhist by the main Tibetan traditions, it shares so many similarities and practices with mainstream Tibetan Buddhism that some scholars such as Geoffrey Samuel see it as "essentially a variant of Tibetan Buddhism". Yungdrung Bon is closely related to Nyingma Buddhism, and includes Dzogchen teachings, similar deities, rituals and forms of monasticism.
