Purification, often referred to as cleansing, is the process of removing impurities or contaminants from a substance or environment. This can apply to various contexts, including water purification, where harmful bacteria and chemicals are eliminated to make water safe for drinking. In spiritual practices, purification may involve rituals aimed at cleansing the mind and body of negative energies. Cleansing can also refer to personal hygiene practices, such as washing hands or bathing, which help prevent the spread of illness. In the context of spirituality, purification rituals, like those in Hinduism or Buddhism, aim to achieve mental clarity and emotional balance.
