A "Thangka," also known as "Tangka", "Thanka" or "Tanka" (Nepali pronunciation: [ˈt̪ʰaŋka]; Tibetan: ཐང་ཀ་; Nepal Bhasa: पौभा) is a Tibetan silk painting with embroidery, usually depicting a Buddhist deity, scene, or mandala of some sort. The thankga is not a flat creation like an oil painting or acrylic painting but consists of a picture panel which is painted or embroidered over which a textile is mounted and then over which is laid a cover, usually silk. Generally, thankgas last a very long time and retain much of their lustre, but because of their delicate nature, they have to be kept in dry places where moisture won't affect the quality of the silk. It is sometimes called a scroll-painting.

These thangka served as important teaching tools depicting the life of the Buddha, various influential lamas and other deities and bodhisattvas. One subject is The Wheel of Life, which is a visual representation of the Abhidharma teachings (Art of Enlightenment).

To Buddhists these Tibetan religious paintings offer a beautiful manifestation of the divine, being both visually and mentally stimulating.
