Rinpoche, also spelled Rimboche and Rinboku, is an honorific term used in the Tibetan language.
It literally means "precious one", and may refer to a person, place, or thing—like the words "gem" or "jewel".
The word consists of rin (value), po (nominalizing suffix) and chen (big).
The word is used in the context of Tibetan Buddhism as a way of showing respect when addressing those recognized as reincarnated, older, respected, notable, learned and/or an accomplished Lamas .
Nyingma traditional histories consider their teachings to trace back to the first Buddha Samantabhadra (Güntu Sangpo) and Indian mahasiddhas such as Garab Dorjé, Śrī Siṃha and Jñānasūtra.
Traditional sources trace the origin of the Nyingma order in Tibet to figures associated with the initial introduction of Buddhism in the 8th century, such as Padmasambhava, Yeshe Tsogyal, Vimalamitra, Vairotsana, Buddhaguhya and Shantaraksita.
Nyingma teachings are also known for having been passed down through networks of lay practitioners .
