Ksitigarbha is one of the four principal bodhisattvas in East Asian Mahayana Buddhism. The others are Samantabhadra, Manjusri, and Avalokiteśvara.At the pre-Tang dynasty grottos in Dunhuang and Longmen, he is depicted in a classical bodhisattva form. After the Tang, he became increasingly depicted as a monk carrying Buddhist prayer beads and a staff.His full name in Chinese is Dayuan Dizang Pusa. This name is a reference to his pledge, as recorded in the sutras, to take responsibility for the instruction of all beings in the six worlds in the era between the parinirvana of the Buddha and the rise of Maitreya. Because of this important role, shrines to Ksitigarbha often occupy a central role in temples, within the memorial halls or mausoleums.
