A thangka, also known as tangka, thanka or tank is a painting on silk 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, thangkas last a very long time and retain much of their luster, but because of their delicate nature, they have to be kept in dry places where moisture wont affect the quality of the silk. It is sometimes called a scroll-painting.
These thangkas are served as important teaching tools depicting the life of the Buddha, like various influential lamas, deities and bodhisattvas. One subject is The Wheel of Life, which is a visual representation of the Abhidharma teachings (Art of Enlightenment).
