Evolution of Narasimha-Hiranyakasipu story from Rig Vedic parable of Indra killing Namuci

 

Vedic narrative of Indra and Namuci, Rig Veda 8.14.13, is the conceptual precursor to the Narasimha-Hiranyakasipu story in puranas.

The ancient Vedic narrative of Indra and Namuci, was first mentioned in the Rig Veda 8.14.13. It was expanded in the Satapatha Brahmana 12.7.3, which was further more expanded in the Section 43 of Shalya Parva in the Mahabharata. And, finally, it was adopted in the Puranas and retold in the Narasimha-Hiranyakasipu story.

a) In the Rig Vedic version (Rig Veda 8.14.13), Indra simply beheads Namuci with the foam of the waters (apām phena). It does not explicitly define whether foam is categorized as wet or dry. And, there is no mention killing at twilight time.

अपां फेनेन नमुचेः शिर इन्द्रोदवर्तयः । विश्वा यदजयः स्पृधः ॥
apām phenena namuceḥ śira indrod avartayaḥ | viśvā yad ajayaḥ spṛdhaḥ ||

English translation:

“You have struck off, Indra, the head of Namuci with the foam of the waters, when you had subdued all your enemies.”

b) The Satapatha Brahmana 12.7.3 explains that because Namuci exacted a vow from Indra that Indra would not slay him "neither by day nor by night, neither with staff nor with bow, neither with the palm of his hand nor with the fist, neither with the dry nor with the moist!". Later, Indra killed him at the twilight time (when the night was clearing up, and the sun had not yet risen) with foam, which is neither dry nor wet.

In this version, the concept of Brahmahatya was not mentioned.

——

c) The Section 43 of Shalya Parva in the Mahabharata repeats the *Satapatha Brahmana*'s story, duly adding the concept of Brahmahatya (the sin of killing a being).

When Indra beheads Namuchi with foam, the severed head relentlessly pursues him, demanding justice for the broken treaty. To cleanse himself of this sin, Indra must perform sacred baths and give gifts at the confluence of the Sarasvati and Aruna rivers.

——

d) In the puranic Narasimha-Hiranyakasipu story, Hiranyakasipu extracted boons from Brahma so he could not be killed by man or animal, day or night, indoors or outdoors, on earth or sky, or by any weapon. Vishnu circumvented this as Narasimha (half-man, half-lion) at twilight on the threshold of the palace, placing the demon on his lap and using his nails (not a manufactured weapon).

——

Interestingly, the concept of Brahmahatya (the sin of killing a being) is omitted in the puranic Narasimha-Hiranyakasipu story.

Perhaps, the scholars who composed Puranas, might have thought that Narasimha is an incarnation of the Supreme Deity (Vishnu), the act of destroying Hiranyakasipu is viewed as an establishment of Dharma and the liberation of the demon. There is no sin, curse, or subsequent cleansing required, as the Supreme Lord is inherently beyond karma.
