On this day, people generally greet by smearing each other with colour and shouting out "Holi Hai" or simply "Happy Holi!"
Light snacks such as Pakoras, Gujia, and milk-based cool drinks (Thandai), are often served at Holi parties.
Demon King Hiranyakashyap demanded that everybody in his kingdom should worship him.
However, his pious son, Prahlad became a devotee of Lord Vishnu. Hiranyakashyap wanted his son to be killed.
He asked his sister Holika to enter a blazing fire with Prahlad in her lap, since Holika had a boon which made her immune to fire.
Story goes that Prahlad was saved by Lord Vishnu himself for his extreme devotion, and evil minded Holika was burnt to ashes, which is why a day before Holi, 'Chhoti Holi' is celebrated with a huge bonfire.
