Punctuating this ritual calendar are two events, known as Nyepi and Galungan.On Nyepi, which is observed once each solar year (in the Indian Hindu calendar), which is different from the 210-day Balinese year. On that occasion, people are expected to fast, remain silent, and meditate from 6 am to 6 pm, so as to reflect on the state of their lives.It is a time of spiritual renewal.During this time people do not work, keep lights down, do not play television or other appliances much, nor go on the streets or on the beach.On the day after Nyepi people resume normal activities, and perform some rituals together and seek harmony with each other.In preparation for Nyepi, 3 or 4 days before it people perform a ritual known as Melasti, in which they go to a pura near the sea to worship Sang Hyang Widhi Warsa, the highest god in the cosmos. This ritual purifies sacred objects kept in the temple for ceremonies.
