Some of the devotees do not even take a drop of water and keep vigil all night. It is a major festival in Hinduism, and this festival is solemn and marks a remembrance of "overcoming darkness and ignorance" in life and the world. It is observed by remembering Shiva and chanting prayers, fasting, and meditating on ethics and virtues such as self-restraint, honesty, non-injury to others, forgiveness, and the discovery of Shiva. The ardent devotees keep awake all night. Others visit one of the Shiva temples or go on pilgrimage to Jyotirlingams.
