A “Thangka,” also known as “Tangka”, “Thanka” or “Tanka” : is a Tibetan silk painting with embroidery, usually depicting a Buddhist deity, famous scene, or mandala of some sort. The thankga is not a flat creation like an oil painting or acrylic painting. Rather, it 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.
Maṇḍala is a Sanskrit word that means “circle”. In the Hindu and Buddhist religious traditions their sacred art often takes a mandala form. The basic form of most Hindu and Buddhist mandalas is a square with four gates containing a circle with a center point. Each gate is in the shape of a T.
These mandalas, concentric diagrams, have spiritual and ritual significance in both Buddhism and Hinduism.The term is of Hindu origin and appears in the Rig Veda as the name of the sections of the work, but is also used in other Indian religions, particularly Buddhism. In the Tibetan branch of Vajrayana Buddhism, mandalas have been developed into sandpainting. They are also a key part of anuttarayoga tantra meditation practices.
