Many of these involve interaction between the sangha and the laity. For example, when a lay person gives a monk food, they gain merit. Acting in a moral manner, teaching the proper belief, preaching, and chanting also gain an individual merit. Worship of the Buddha can also bring merit. The notion of merit plays the largest role in Theravada Buddhism.
