Most Cambodians are Theravada Buddhist. Theravada Buddhism is one of the two main Buddhist sects and is practiced also in Thailand and Laos. Khmer Buddhists believe in karma and reincarnation—that is, they believe that today’s actions will affect their lives in the future, either in this or future lives. The Buddhist religion allows Cambodians a way to gain merit so they may be reborn to a better life. They gain merit by good acts and religious deeds that include acting properly, celebrating holy days, and taking food to the monks at the temple.
