This Bon Spirit mask may well represent Buddha, it’s at the very least 19th Century and just the most extraordinary item and a tongue Kiss would be proud of. It has a presence of its own and is human face size so perhaps had some significance other than hanging above a door, although that is more than significant in itself. An historic repair to the tongue, original surface paint and condition. It was suggested too that it represents Kali but whom so ever, you have to remember the way Buddhism and Hinduism share similarities. Bon religion is a native religion in Tibet, dating back more than 3,800 years. Its founder was a master of gShen rab mi bo who born in the Ali region of Tibet in 1917BC. Before Buddhism was officially introduced to Tubo in the 7th century, various tribes on the Tibetan plateau generally believed in Bon religion. Buddhism hand Hinduism agree on karma, dharma, moksha and reincarnation. They are different in that Buddhism rejects the priests of Hinduism, the formal rituals, and the caste system. Buddha urged people to seek enlightenment through meditation. According to the modern scholar Geoffrey Samuel, while Bon is "essentially a variant of Tibetan Buddhism" with many resemblances to Nyingma, it also preserves some genuinely ancient pre-Buddhist elements. David Snellgrove likewise sees Bon as a form of Buddhism, albeit a heterodox kind. Heterodox means not conforming with accepted or orthodox standards or beliefs.
