Holika Dahan is an important part of Holi which signifies the victory of truth over darkness. In Hindu mythology, Holika was a woman who could withstand fire. She entered fire carrying Prahalad, a devotee of Lord Vishnu, whose father was intent on killing him, but was instead burned to a crisp while Prahlad was saved.
Being an Indian tradition, the mythology of course it takes more than one paw. was once a demon king Hiranyakashipu , who claimed that the whole universe worshiped him as God. Yet his ambition to climb the divine did not seem to have much success, so much so that his son, Prahlad became a devotee of Vishnu , competition.
This infuriated his father, who tried in every way to kill his offspring, but thanks to the protection of God, his plans continued to fail. One day the demon king decided to send his sister Holika who had the power to not burn in the fire, to take the coveted murder. Holika took Prahlad her arms and began to burn.
But once again, Vishnu intervened, saving the devotee Prahlad while Holika, unaware that his immunity to fire only worked if it was to burn alone, died devoured by the fire. This triumph of good over evil, is the night of the full moon, before Holi, when huge bonfires are lit by reproducing the fire that burned alive Holika.
