Story time: Why festival of colours was named 'Holi'
Once upon a time, there was a demon king called Hiranyakashyap, who ruled over earth
But to his disappointment, his own son Prahlad became a devotee of Lord Vishnu!
He tried to kill Prahlad by crushing him under an elephant's foot, and even throwing him off a cliff
But Vishnu protected the boy from all his father's attempts
Frustrated, Hiranyakashyap finally turned to his sister Holika
Holika was blessed with a boon that allowed her to enter fire and come out unharmed
So she asked little Prahlad to sit on a pyre with her. But for the boon to work, Holika needed to enter the fire alone
Holika was burnt to ashes, while Prahlad - who had been chanting Vishnu's name - emerged unhurt!
