The painting of colored sand mandala was approved by the State Council in 2014 and included in the fourth batch of national intangible cultural heritage list. The painting of colored sand mandala originated from the traditional art of Tashilhunpo Monastery in Shigatse City, Tibet Autonomous Region, China. Mandala originated from the Indian Tantric Buddhism and is one of the objects of worship during the practice of Tibetan Tantric Buddhism. It is made of seven-colored sand particles piled up according to strict proportions, structures, and contents. After outlining the outline on the pedestal, it starts from the center and gradually spreads out in alternating squares and circles. In addition to sand masonry, mandala can also be made in different ways such as hand-painting and wood carving. Mandala originated from the Indian Tantric Buddhism. It is a place where the Tantric deity and his family gather. It is an object that must be worshipped during the practice of Tibetan Tantric Buddhism. In layman's terms, it is the home of Buddha. It is called "Ji Kuo" in Tibetan, which means "middle wheel" and "wheel circle". When translated into Chinese, mandala also has different transliterations and translations such as mandala and altar. According to Buddhist scriptures, in order to prevent the invasion of the "demons" of the outside world, in the practice of the Indian Tantric Buddhism, boundaries were drawn or earthen altars were built at the practice site, and Buddha statues were placed on them, indicating that all Buddhas gathered or the wheel was complete. Later, the altars and boundaries set during the practice were called mandalas or mandalas. Mandalas use three-dimensional or flat square and round geometric shapes to shape and paint statues and instruments of gods, representing the altars and palaces of the gods, and metaphorically describing the structure of the Buddhist world. Since more than 2,500 years ago, when the Buddha personally taught his disciples to make sand mandalas, this exquisite religious art has been passed down from generation to generation without interruption. In the 11th century, it was introduced from northern India to Tibet and has been preserved to this day. The painting of colored sand mandalas is one of the unique and exquisite religious arts in Tibetan Buddhism. During large-scale religious activities, the lamas in the temples use millions of grains of sand to depict the strange Buddhist world. This process may last for days or even months. From an artistic point of view, the whole painting has a rigorous structure and rich colors. With the help of sand, a medium with a sense of layering and heaviness, the religious significance is well expressed. Whether it is the Buddha sitting in the center, or the creatures with different expressions around the Buddha, or the circle of ethereal air surrounding the world, they all have their own spirits and harmoniously constitute the world of 0. What is even more amazing is that this unique creative method limits the possibility of too much change, so the whole painting must be completed in one go, just like the monks silently writing out the worldview that they have mastered in their minds.
