During the reign of Kanishka, Buddhism was divided into Mahayana and Hinayana branches. Mahayana Buddhism emerged as a more inclusive form of Buddhism that emphasized the concept of Bodhisattva, individuals who postpone their own enlightenment to help others achieve it. Hinayana, on the other hand, focused on individual enlightenment and adherence to the original teachings of the Buddha. Kanishka was a Kushan emperor who ruled during the 2nd century CE and is known for his patronage of Buddhism. His reign was a significant period of Buddhist art and literature, and it was during this time that the division between Mahayana and Hinayana developed.
