The Ganhadra school of art came into existence in the Mahayana sect. The Mahayana sect is one of the two major branches of Buddhism, with the other being the Hinayana sect. The Mahayana sect emerged as a distinct form of Buddhism around the 1st century CE and spread throughout Asia, including areas like China, Tibet, Japan, and Korea. The Ganhadra school of art is associated with the Mahayana sect and is known for its diverse artistic representations of the Buddha and Bodhisattvas. These artistic expressions were important in spreading the teachings of Buddhism and inspiring devotion among the followers of the Mahayana sect.
