Sunda Wiwitan is a traditional religion that comes from the Sundanese people who live in Indonesia. It involves a belief in God as the creator of everything, but also involves a lot of nature worship. This means that followers of Sunda Wiwitan respect and honor things like trees, mountains, and rivers, because they believe these things were created by God and are important parts of the world.
Sunda Wiwitan also has many rituals and ceremonies that followers participate in throughout the year. These might involve offerings of food or flowers, or may include singing and dancing. There are also certain times of the year when followers of Sunda Wiwitan will fast, meaning they won't eat or drink for a certain period of time in order to show devotion to their religion.
Sunda Wiwitan is important to many Sundanese people because it helps them feel connected to their culture and their ancestors. They believe that by honoring God and nature in this way, they will ensure good things will happen to their families and communities.
