What is "holika"

Holika was a demoness in Hindu Vedic scriptures, who was burnt to death with help of God Vishnu. She was the sister of King Hiranyakashipu and aunt of Prahlad.

The story of Holika dahan (Holika's death) signifies the triumph of good over evil. Holika is associated with the annual bonfire on the night before Holi, the Hindu festival of colors.
