The Lhotshampa people are an ethnic group of Nepalese ancestry in Bhutan. Their caste system is still intact today, hierarchically classifying several hereditary groups. In this video, Lachuman Tahapa from Riserboo in Tsirang gives an account of the origins of the Rai caste of the Lhotshampa. A woman conceived a baby girl, and gave birth to it. After she grew up, the daughter told her mother that she also wanted a daughter. She asked her mother how to become pregnant, and received instructions. The daughter did as she was told, but it soon became obvious that she would not become pregnant in that way. They went searching for a star to be the husband of the daughter. They met an ugly star, but they did not accept him as a husband. They felt frustrated, and decided to go back. On their way home, they reached a place where everything had been dried up from heat. There was no water to drink, and the daughter was so thirsty that she was on the verge of dying. But then, they saw the place where the ugly star had peed, and the daughter drank the star pee. The moment she drank it, she was back to normal and conceived a baby. With that baby the Rai caste originated.
