Rinpoche

Rinpoche or Rimpoche (Tibetan:ར; /rin'potʃe/) is a Tibetan Buddhist religious/theological honorific title. "Rinpoche" literally means "precious one". The title is generally reserved for tulkus (incarnate lamas) and those recognized by the proper authorities within a lineage as "choje lamas" ("superior dharma masters").

This is an honorific term applied to lamas in Vajrayana (Tibetan) Buddhism. It literally means "greatly precious" and is given to masters who are highly valued for their spiritual knowledge. A Rinpoche is often believed to be the reincarnation of a lama, guru, or even a bodhisattva or a buddha. For introductions to some Rinpoches, go here.
