Balinese Hindu people take part in a cleansing ceremony called “Melasti”, in Denpasar, Bali, Indonesia, 25 March 2025. Melasti is a purification ritual where Balinese Hindus cleanse themselves and their sacred objects in the ocean to purify and renew spiritually, symbolizing the washing away of impurities and starting anew. It typically precedes Nyepi, the Day of Silence, marking the Balinese New Year. Balinese will celebrate Nyepi Day on 29 March 2025, during which Hindus on the island of Bali are not allowed to travel, work, light lamps, cook, or do any other activities. (Photo by Made Nagi/EPA)
