Ritual cleanliness refers to the practices and beliefs surrounding purification in various cultures and religions. It often involves specific actions, such as washing or abstaining from certain foods, to achieve a state of spiritual or physical purity. This concept is significant in traditions like Judaism, where kosher laws dictate dietary practices, and in Islam, where wudu is performed before prayers. These rituals can symbolize respect, devotion, and a connection to the divine. They may also serve to create a sense of community among followers, as shared practices reinforce cultural identity and moral values.
