Maha Shivaratri is a major Hindu festival, but one that is solemn and theologically marks a remembrance of "overcoming darkness and ignorance" in life and the world, and meditation about the polarities of existence, of Shiva and a devotion to humankind. It is observed by reciting Shiva-related poems, chanting prayers, remembering Shiva, fasting, doing Yoga and meditating on ethics and virtues such as self-restraint, honesty, noninjury to others, forgiveness, introspection, self-repentance and the discovery of Shiva. The ardent devotees keep awake all night. Others visit one of the Shiva temples or go on pilgrimage to Jyotirlingam shrines. Those who visit temples, offer milk, fruits, flowers, fresh leaves and sweets to the lingam. Some communities organize special dance events, to mark Shiva as the lord of dance, with individual and group performances. According to Jones and Ryan, Maha Sivaratri is an ancient Hindu festival which probably originated around the 5th-century.
