The Temple of the Tooth in Kandy has established the International Buddhist Museum (IBM) to showcase the spread of Buddhism in Asia and around the world. This is the only museum in the world that displays the spread of Buddhism.

By the year 2600, the year of Sambuddhatva Jayanthi, Buddhism had developed its status from a simple philosophy of life to a ritualistic religious system derived from early Buddhist thought. Buddhism has spread to India, the birthplace of the Buddha, as well as to various parts of Asia, the Southeast, and the East. The message of the Buddha is now being explored in the broader context of the modern world. It is interesting to note the different methods used by the respective countries, both Theravada and Mahayana, in the practice of Buddhism.
