Balinese Hindus place beautiful offerings, known as canangsari, in front of their houses. Mixtures of flowers, leaves, fruit, rice and crackers are laid out in handmade boats or trays of betel leaves, called a porosan. Each offering must be in a porosan and contain an areca nut and a lime. These key items represent the three manifestations of the Hindu supreme spirit, Sanghyang Widhi: Brahma the creator, Vishnu the preserver and Shiva the destroyer. Offerings are set out on shrines, to appease the good sprits, and on the ground, to appease the evil sprits. Often lighted incense is placed in the canangsari, sending beautiful fragrances out into the morning air.
