Illnesses and treatments are an inevitable part of life in the daily life of the neo-confucianist Dou Ke-qin whose life outlook on the treatment and recognition of diseases was influenced by his neo-confucianist conception. He claimed that diseases can be conquered by spiritual force formed on the basis of Neo-Confucianism and can be recovered by peace of the heart and moral merits and can be seen as an approach of self-accomplishment. He opposed Taoist and Buddhist ideas of life preservation and keeping fit by taking the advantages of external mystic force, and stressed that his own diseases and that of his relatives can be cured by the filial affection advocated by the Neo-Confucianism.
