The legend of Narasimha from Vishnu puran:

Hiranyakashipu (golden-haired one) after his brother Hiranyaksha (golden-eyed one) was killed by Vishnu, he vowed revenge on the Gods.

Hiranyakashipu performed penance for thousands of years to attain supernatural powers meditating on the self-created Brahma!

He asked for the boon of immortality but Brahma refused saying "there can be no creature of a form which can be immortal, I myself am not, so ask for any other boon!"

Hiranyakashipu then asked Brahma that he would never be killed by any humanoid form, animal, with weapons or bare-handed, neither in the day nor at night, neither outside nor inside, neither above nor below! Brahma affirmed "so be it!"

Hiranyakashipu conquered the three worlds and sat on the throne of the king of gods Indra, but unlike Indra the great he was arrogant, lived like a tyrant and made all the gods including Indra, Vishnu ,Brahma and Shiva bow before him! for none of the humanoid forms could defeat him!

But Hiranyakashipu had a son, his name was Pralhada and though he was just a child he was not fond of material pleasures.

Pralhada always supported Vishnu in the matter of his uncle's death and this angered Hiranyakashipu greatly. Hiranyakashipu tortured Prahrada everyday for he did not heed to his father's words.

One day, Hiranyakashipu beholding a pillar near him mocked his son asking him "if the almighty is everywhere, is he in this pillar too?"

Prahrada said yes! and in anger Hiranyakashipu broke the pillar with a single blow from his mighty fist.

But then they heard a crackle, like the crackling of thunder! and lo came out from the pillar the incredible Narasimha (man-lion). His form was neither human nor of an animal.

Narasimha and Hiranyakashipu entered into a fierce battle, and finally Narasimha gained the upper-hand by fighting with his claws as he was neither armed nor bare-handed. He took him near the entrance of the hall and sat below the arch... neither outside nor inside.

He forcefully kept Hiranyakashipu on his thigh..neither above nor below.

Narasimha then tore Hiranyakashipu apart with his claws and wore his intestines as a garland of victory at twilight, which is neither day nor night!

🙏 Namo Narasimha 🙏
