Acharya Prashant explains the significance of Holi by recounting the story of the demon king Hiranyakashipu and his son Prahlad from the Vishnu Purana. He describes how the king, through intense penance, obtained a complex boon from Lord Brahma that made him nearly immortal by specifying conditions under which he could not be killed. This power led to extreme arrogance, with the king demanding that he be worshiped instead of God. However, his young son Prahlad remained a steadfast devotee of the Truth, refusing to submit to his father's ego despite threats and attempts on his life.
