A monk is a man who devoted part or all of his life to a religion. The word comes from Ancient Greek, and can be translated as "solitary". In Greek, the word can be used for men and women alike, but in English,a woman who does the same is called a nun. Monks practice asceticism. They either live alone, or together with other monks who share the same ideals. Monks can be found in different religions, most often in Buddhism, Christianity, Hinduism, Jainism and Taoism.
