Tsaklis, or tsakalis, are small paintings of the size of a postcard or somewhat smaller or larger that have been used in Tibet and Mongolia in religious rituals for centuries. They have been painted on thick hand made paper, or on paper consisting of many layers glued together. Also tsaklis painted on canvas exist; they are also called miniature thangkas. On these tsaklis the various deities are pictured that exist in Tantric Buddhism, the indigenous Bon religion, as well as the folk relgion. They therefore reflect the world of gods, protectors and demons in Tibet and Mongolia. This book shows over 300 pictures of tsaklis, together with commentary.
