The sixth century BC was pivotal in the history of the world. Babylon conquered Jerusalem (586), thus ending the Israelite monarchy. Mahavira (599-527), also known as Vardhamāna, known to Jains as the 24th fordmaker, founded the Jain religion. Siddhartha Gautama (c. 563-480) founded Buddhism, one of the most prevalent religions in the world. Buddhism today boasts almost 500 million adherents worldwide, and others practice Buddhist meditation and hold Buddhist beliefs without self-identifying with the religion. Gautama is variously known as the Sakyamuni, the Tathagata, and the Buddha.
Any student of world religions should know something about the work of the Buddha. Christians should have an idea of what Buddhism is, and how to best minister to the followers of Gautama.
