The Luwa-Prai village of Ba Gum is considered to be the most orthodox and the most respected among Luwa communities. The Luwa-Prai village follows a religious system that differ them from other Luwa villages: there are two families of ghosts. The two separate ghosts act like clans, meaning they split the villagers in half and into two last names. This perpetuates and acts as an enforcer of the ghostly law that bans intermarriage within the same ghost family. 

This tradition that prevents inbreeding was created in the first few years of the formation of the Luwa- Prai village. With the amalgamation of the Huoy Bo and Norng Nan villagers, this ghostly law came into existence. This prompted an increase in Luwa population, which then resulted the second migration, of a small percentage of the village, from Ba Gum to Nam Pae. This process of expansion and migration resulted in numerous villages scattered across Southeast Asia that are all Luwa.  

The Ba Gum villagers believe in powers beyond the natural: ghosts. They revere the forest, water, and all things natural for their spirits. Within the multitude of ghosts, there are two in which protect the village as a whole. These two ghosts are known as the Ah Ye and the Ah Pe. They divide the village in half, serving as last names. Under these two ghosts, there are subsets of minor spirits that protect each individual household. There are a total of eighteen ghosts whom the villagers worship. 

            The ghosts of Ah Ye and Ah Pe serve as last names that each person inherits and is passed down through ancestry. Attached to each ghost is an elder. These elders are known as “ghost doctors”. He is a leader who the villagers count on to upkeep traditions, heal sicknesses, and lead their souls. The elder is the epitome of the Luwa man and has full knowledge of the layers of the Luwa culture. He decides the timing of all rituals and is the leader of the souls that belong to his ghost clan. They are trained and, supposedly, selected by ghosts from a young age. In Thai, the elder is known as “Moh Reed”. The word “Moh” means doctor. The word “Reed” derives from the term “Ja Reed” which means tradition. Together the term “Moh Reed” means a doctor who specializes in tradition. 

In Ba Gum there are two leaders, one for the Ah Ye and the other for the Ah Pe clan. They advise people in every aspect of their lives. Their approval is needed when villagers want to build a new house. This is because each piece of land is attached with a different ghost who has different needs and restrictions. They know the ways of each spirit. They know what offerings must be given to satisfy the river ghost in order to maintain water supply. Or when outsiders enter the village, a ceremony must be performed. There must be offerings to the water ghost who will grant safe passage into the village. If this ritual is not performed, potential harm may come to the villagers. 

This is the most traditional form of Ba Gum culture, but in the present day this belief interferes with modern beliefs. Because of this, the ghost doctors must be able to control and aid their people to survive in the current world.
