Pecha
Pecha is a Tibetan word meaning "book", but in particular, refers to the traditional Tibetan loose-leaf books such as the kangyur, tengyur, and sadhanas. Pechas sometimes have top and bottom cover plates made of wood, cardboard, or other firm materials, and are often seen wrapped in cloth for protection. The word pecha has entered common use in other languages such as English in the Tibetan Buddhist community, evident online in discussion forums and software products that include the word in their names.
