The practice is also known as Kirat Veda, Kirat-Ko Veda or Kirat Ko Ved. According to some scholars, such as Tom Woodhatch, it is a blend of shamanism, animism (e.g., ancestor worship of Yuma Sammang/Tagera Ningwaphumang and Paruhang/Sumnima), and Shaivism. It is practiced by about 3.17% of the Nepali population as of 2021. It has the religious scripture and folk literature of the Kirat people of Nepal and India.
