Acharya Prashant explains the significance and symbolism of Holi, a prominent Indian festival celebrated globally. He describes the festive atmosphere where people smear each other with colors, play music, and set aside enmities to embrace one another. He highlights the ritual of lighting a wood pile on the eve of Holi, which symbolizes a deeper spiritual narrative from the Vishnu Purana involving the demon king Hiranyakashipu and his son Prahlad.
