Holy Cave: Devotees pray during a family ceremony in front of the famous Goa Lawah (Bat Cave) Hindu temple in Persinggahan village in Bali’s Klungkung Regency. Over seven million bats live in the deep cave, say local officials, and are considered holy once residing there – come dusk, when the sky darkens as the fruit-eating creatures fly out en masse to surrounding forests to forage, they return to mere mortal status.
