Suicide is a serious social problem in modern Korean society. In early Buddhism, including suicide, teachings about death are frequently offered. The agony of death is a typical existential distress, and meditation on death is an important practice. Various suicide cases appear in the scriptures and chapters of early Buddhist literature. Suicide, a type of murder, is seen as an evil act that intentionally cuts the chance of being born as a human being, and the background of suicide is the desire to die, which is the love of non-existence. Usually, humans choose to kill themselves by means of indulgence. However, saints do not commit murder intentionally, nor do they commit suicide. However, there are cases where a monk who suffers from severe illness accidentally commits suicide because he thinks that he has become Arahan, or during the selection process, he commits suicide to be born in heaven as a result of selection. The Buddha only died as Arahan when his life was cut off after committing suicide, and he did not pay for the wrongdoings of suicide. However, various examples of early Buddhist literature show that suicide is prohibited as an evil act because it is a method of murder.
