Korean religion is a combination of beliefs and ideals that have been adopted from traditional religions. The most predominate religion in South Korea is Buddhism with Christianity coming second. Both religions have a large impact on the daily lives of the Koreans. In addition to the main organized religions, Koreans are adamant followers of Confucianism.
Confucianism is based on a strict set of rules pertaining to social conduct. The underlying understanding of Confucianism is harmony. Harmony in all aspects of life, be it family, business or emotion, is to be obtained in order prevent social disruption. Everyone in society has a purpose and a place, and this should always be remembered and respected. Trust, piety, loyalty, respect and positional distinction are components that are instilled into every aspect of daily life.
Shamanism: The invocation and worship of spiritual deities are the basis of shamanism. Despite several strong attempts to eliminate such beliefs from society, shamanism has become entrenched in modern Korean Buddhist, Christian and Confucian rituals. Shamanism stresses the importance of spiritual existence and relation to every part of nature. Everything has a spirit attached to it, either good or bad that must be appeased in order to maintain harmony.
Korean mudangs, commonly women with the ability to communicate with the spirits, serve as the go-betweens for the spiritual world. When confronted with a problem in life, a mudang will conduct a kut--a ceremony to help appease the spirit -- in order to rejuvenate personal harmony.
For the new generation, however, the influences of shamanism are not so obvious as it used to be, but those have melted deeply in the whole society under the form of various taboos such as "you don't go to someone's funeral if you yourself have recently lost someone close, or, if you are scheduled to be married soon."
