All through the day the devotees keep severe fast, chant the sacred Panchakshara mantra "Om Namah Shivaya", make offerings of flowers and incense to the Lord amidst ringing of temple bells. They maintain long vigils during the night, keeping awake to listen to stories, hymns and songs. The fast is broken only the next morning, after the nightlong worship. In Kashmir, the festival is held for 15 days. The 13th day is observed as a day of fast followed by a family feast.
