Despite several warnings from his father Hiranyakashipu, Prahlada continues to worship Vishnu. His father tries to poison him, get him trampled by the elephants, and put him in a room with venomous snakes, but Prahlada survives each and every time.

Holika, the sister of Hiranyakashipu, has a special shawl that would prevent fire affecting the person wearing it. One day, Hiranyakashipu orders Prahlada to sit on a pyre on the lap of Holika. Prahlad prays to Lord Vishnu to keep him safe. When the fire starts, Holika burns to death, while Prahlada remains unharmed. This incident is celebrated as the Hindu festival of Holi.

After tolerating much abuse from his father Hiranyakashipu, Prahlada is eventually saved by Vishnu in the form of Narasimha, the half-man, half-lion avatar.

The story of Prahlada gives a number of moral instructions such as:

God prevails everywhere. God will always save his devotees. Devotion can be practised at any point of time. Age does not matter. Constant faith in God leads to devotion. The people who are practising evil will be punished.
