Holika
Holika (), sometimes also known as Simhika, was a demoness in scriptures. She was the sister of King Hiranyakashipu and the aunt of Prahlad. The story of "Holika Dahan" (Holika's death) signifies the triumph of righteousness over non-righteousness. Holika is associated with the annual bonfire on the night before Holi, the festival of colors. Legend. According to Hinduism, a king named Hiranyakashipu, like many demons and Asuras, had the intense desire to be immortal. To fulfill this desire, he performed the required Tapas or meditation until he was granted a boon by Brahma. The boon gave Hiranyakashipu five  special powers: he could be killed by neither a human being nor an animal, neither indoors nor outdoors, neither at day nor at night, neither by "astra" (projectile weapons) nor by any "shastra" (handheld weapons), and neither on land nor in water or air. As this wish was granted, Hiranyakashipu felt invincible, which made him arrogant. Hiranyakashipu decreed that only he be worshiped as a god. He punished and killed anyone who did not accept his orders. His son Prahlad disagreed with his father, and refused to worship his father as a god. He continued believing in and worshipping Lord  Vishnu. This made Hiranyakashipu very angry and he made various attempts to kill Prahlad. During one attempt on Prahlad's life, King Hiranyakashipu called upon his sister Holika for help. Holika had a special cloak garment that prevented her from being harmed by fire. Hiranyakashipu asked her to sit on a bonfire with Prahlad, by tricking the boy to sit on her lap. However, as the fire roared, the garment flew from Holika and covered Prahlad. Holika burnt to death, Prahlad came out unharmed. Vishnu appeared in the form of Narasimha (half human and half lion), at dusk (neither day  nor night), took Hiranyakashipu to a doorstep (neither indoors nor outdoors), placed him on his lap (neither land, water nor air), and then eviscerated and killed the king with his lion claws (neither a handheld weapon nor a launched weapon). In this manner, the boon of five special powers granted to Hiranyakashipu was no longer useful. Prahlad and the kingdom of human beings were thus set free from the compulsion and fear of Hiranyakashipu, showing the victory of good over evil. Origin of Holika Dahan. For many traditions in Hinduism, Holi celebrates the death of Holika in order to save  Prahlad. The night before Holi, pyres are burnt in North India in keeping with this tradition. In some parts of India the day is actually called Holika . There are other activities associated with the story of Prahlad, but the burning of Holika is the one most directly associated with Holi. The story as a whole is testament to the power of devotion (bhakta) over the evil represented by King Hiranyakashipu, as Prahlad never lost his faith. The burning of Holika is the most common explanation according to Hindu Puranas for the celebration of Holi. In different parts of India, various  reasons are given for Holika's death: There is also another story behind Holi that involves a burning sacrifice for the sake of love involving Shiva and Kamadev. Before Shiva was married to Parvati, Kamadev (God of Love) and his wife Rati (Goddess of love) tried to help Parvati win Shiva as her husband. Kamadev and Rati shot their arrow at Shiva during his meditations to make him love and marry Parvati. This disturbed Shiva, and caused his third eye to open, its powerful gaze burning Kamadev into ashes, and leaving Rati brokenhearted. Although the arrow did not work, as  it was destroyed in the process, Shiva and Parvati did eventually marry. At the wedding, Rati begged Shiva to bring Kamadev back to her. Shiva agreed, and restored Kamadeva as a virtual image with true emotions.
