Thangka
A thangka, variously spelled as thangka, tangka, thanka, or tanka, is a Tibetan Buddhist painting on cotton, silk appliqué, usually depicting a Buddhist deity, scene, or mandala.
Historically, thangkas were used as teaching aids. A lama or teacher would travel giving talks on Buddha's life and teachings. He would carry with him painted scrolls to convey spiritually significant events, aspects of different deities, or Buddhist concepts.
