Holika Dahan, also known as Choti Holi, is a significant ritual that is part of the Hindu festival of Holi. This ritual is observed on the night before the main day of Holi, and it involves the symbolic burning of a bonfire. The significance of Holika Dahan can be traced back to Hindu mythology, specifically the legend of Prahlad and Holika.

The story behind Holika Dahan is associated with the demon king Hiranyakashipu and his son Prahlad. Hiranyakashipu had received a boon that made him nearly invincible. He became arrogant and demanded that everyone worship him as a god. However, his son Prahlad was a devout follower of Lord Vishnu, which angered Hiranyakashipu. The demon king tried various ways to kill Prahlad, but all attempts failed.

Hiranyakashipu sought the help of his sister Holika, who had a special boon that made her immune to fire. Holika sat in a pyre with Prahlad on her lap, intending to burn him. However, due to Prahlad's unwavering devotion to Lord Vishnu, he was protected, and Holika was consumed by the fire. This event symbolizes the victory of good over evil, as Prahlad's devotion and virtue triumphed over Hiranyakashipu's arrogance and wickedness.

The Holika Dahan ritual is a reenactment of this mythological event. People gather wood and other combustible materials to build a bonfire. Just before lighting the fire, prayers are offered to seek the blessings of Agni, the fire god. The fire symbolizes the burning of negativity, evil, and impurities. People sing and dance around the bonfire, celebrating the victory of good over evil and the triumph of light over darkness.

Holika Dahan also marks the transition from winter to spring, and the bonfire is believed to purify the air and the environment. Additionally, people often throw symbolic items like grains, gud (jaggery), and neem leaves into the fire to ward off any negative influences and promote well-being.

In summary, the significance of Holika Dahan lies in its connection to the mythological story of Prahlad and Holika, celebrating the victory of good over evil, and marking the arrival of spring with the purification of the environment through the bonfire ritual.
