Korean shamanism
Korean shamanism has been looked down on by adherents of other religions, but has over time incorporated and imitated the form and organization of foreign religions such as Buddhism and Confucianism. Foreign religions in turn absorbed elements of shamanism. Shaminism also developed a complementary relationship with Confucianism. Shamanism dealt with abnormal and irregular problems, while Confucian beliefs dealt with regular and everyday problems. Korean shamanism includes rituals used to release rancor from bitter souls and expel bad luck from houses.
