This horizontal banner is part of a Tibetan Buddhist temple decoration that is usually hung by the rafters high along the wall. It depicts the Seven Attributes of Royal Power, or the symbols of a universal monarch (_chakravartin _in Sanskrit)—a wheel, jewel, queen, minister, elephant, horse, and general. These are often part of the offerings invoked during Buddhist rituals, including mandala offerings.
In addition to the Seven Symbols, Mount Meru occupies the central panel and wrathful offerings appear at the far right. The back of the banner contains the inscription “nub byang thur ‘tshams,” which translates to “the northwest corner.”
