In Cambodia, the three days of celebration are centered on religious observances. The vast majority of Cambodians are Theravada Buddhists, and during this time they visit temples to complete various rituals. These include merit-making activities, such as praying and offering food to monks in exchange for a blessing. They also build sand hills on the temple grounds. These symbolize the heavenly “stupa” where relics of the Buddha’s earthly remains are believed to be kept.
