The Sand Mandala (Tibetan: དཀྱིལ་འཁོར།, Wylie: dkyil ‘khor; Chinese: 沙坛城;pinyin: Shā Tánchéng) is a Tibetan Buddhist tradition involving the creation and destruction of mandalas made from colored sand. A sand mandala is ritualistically dismantled once it has been completed and its accompanying ceremonies and viewing are finished to symbolize the Buddhist doctrinal belief in the transitory nature of material life.
Historically, the mandala was not created with natural, dyed sand, but granules of crushed colored stone. In modern times, plain white stones are ground down and dyed with opaque inks to achieve the same effect. Before laying down the sand, the monks assigned to the project will draw the geometric measurements associated with the mandala. The sand granules are then applied using small tubes, funnels, and scrapers, called chak-pur until the desired pattern over-top is achieved. Sand mandalas traditionally take several weeks to build, due to the large amount of work involved in laying down the sand in such intricate detail. It is common that a team of monks will work together on the project, creating one section of the diagram at a time, working from the centre outwards.
