The Sand Mandala (Tibetan: དཀྱིལ་འཁོར།; kilkhor) is a Tibetan Buddhist tradition involving the creation and destruction of mandalas made from colored sand. A sand mandala is ritualistically destroyed 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 coloured 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, 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 center outwards.

Philip Glass (born January 31, 1937) is an American composer. One of the highest profile composers writing "classical" music today, he is often said to be one of the most influential composers of the late 20th century. His music is also often controversially described as minimalist, along with the work of the other "major minimalists" La Monte Young, Terry Riley and Steve Reich.

He has lately distanced himself from the "minimalist" label, describing himself instead as a composer of "music with repetitive structures." Though his early mature music shares much with what is normally called "minimalist", he has since evolved stylistically. Currently, he describes himself as a "Classicist", pointing out that he is trained in harmony and counterpoint and studied such composers as Franz Schubert, Johann Sebastian Bach and Wolfgang Amadeus Mozart with Nadia Boulanger.

Glass is a prolific composer: he has written works for the musical group which he founded, the Philip Glass Ensemble (with which he still performs on keyboards), as well as operas, musical theatre works, ten symphonies, eleven concertos, solo works, chamber music including string quartets and instrumental sonatas, and film scores. Three of his film scores have been nominated for Academy Awards.
