How Vishnu and Shiva became one body
Vishnu and Shiva merge into a single form — to end a dispute among devotees, to kill Guhasura whom neither could kill alone, or at Parvati's prayer to reconcile two serpent kings. Shiva is the right half, Vishnu the left, in every telling.
The most general account says the joint form arose when devotees of Shiva and of Vishnu argued over which god was supreme, and the two gods merged to show that the quarrel had no object. The earliest surviving images are sixth-century, at Badami, and the form spread across India and into Khmer Cambodia. Pattanaik places the Harihara cult among the reconciliation efforts that gained popularity around the fifteenth century, when Shaiva and Vaishnava communities marked themselves apart by forehead marks, sacred leaves and marriage rules; attribute that framing to him.
What is different here:
Base telling; no demon, no goddess, no named place.
South India · Harihar, Davanagere district, KarnatakaSmarta
The Hoysala temple at Harihar tells it as a demon story. Guha, ruling the country between Uchchangi Durga and Airani, won from Brahma a boon that neither Vishnu nor Shiva could kill him on his own. So the two became one, Harihara, came down at Kudalur where the Tungabhadra meets the Haridra, and killed him. The temple was built about 1223–24 by Polalva, minister of the Hoysala king Narasimha II, and its image holds Shiva's emblems in the right hand and Vishnu's in the left.
What is different here:
Brahma's boon creates the need for the merger, making it a three-god story; the merger is a weapon, not a reconciliation.
South India · Sankarankovil, Tenkasi district, Tamil NaduShaiva
At Sankarankovil the reconciler is the goddess. Two serpent kings, Sangan who worshipped Shiva and Padman who worshipped Vishnu, disputed which god was greater and went to Parvati, who knew the two were one. She undertook a ten-day penance to call both at once; celestial women came as cows to attend her, so she is Gomathi, 'lady of the cows'. Shiva and Vishnu appeared as a single figure, Sankara Narayanar, Vishnu on the left and Shiva on the right. A self-born linga was later found in an anthill among serpents by a local man and the king raised the temple; the district calls the image a symbol of the unity of Shaivism and Vaishnavism, and the Aadi Thapasu festival in July re-enacts the penance.
What is different here:
Parvati/Gomathi replaces Brahma as the agent; the merger is a vision granted to a goddess, tied to the anthill linga and the Aadi Thapasu festival.
On the Kailasa temple at Ellora the form stands in the eastern gallery and on the lower storey of the Nandi pavilion: Vishnu's left half with discus or conch, Shiva's right half with matted crown and trident or staff, and the two mounts, Nandi and Garuda, flanking the single body.
What is different here:
Iconographic version only; Ellora carves it inside a Shiva temple.
