For this discussion board post, look specifically at the way the role of the Bodhisattva became the ideal within Mahayana Buddhism, in contrast to the arhat, which is the ideal within Theravada. Explain some of the differences between the Bodhisattva and the arhat, and why you think there was a shift in emphasis. These differences are discussed within the textbook and lectures. The goal of this discussion board is to ensure you can articulate the differences between similar, but different religious phenomena and that you can survey larger changes within a religious tradition, trying to determine causes for change.
