The two names of Savitr's verse as two wives of Brahma: Savitri comes late to the sacrifice at Pushkar, Brahma marries the cowherd girl Gayatri, Savitri curses the gods and goes up the hill.
At Pushkar, with Bhrigu, Pulastya, Marichi and Narada as priests, Brahma sends for Savitri. She is still preparing the house and will not come until Lakshmi and the other goddesses arrive. Brahma, angry that the time is passing, has Indra fetch a cowherd's daughter who sells milk and butter; Vishnu tells him to marry her and she is named Gayatri. Savitri arrives, rebukes Brahma, and curses him to be worshipped only in Karttika; she also curses Indra, Vishnu, Rudra, Agni, the priests and the goddesses. Gayatri answers each curse with a boon. Vishnu praises Savitri, and she withdraws to a mountain.
At Pushkar the wife who came late is shown still sitting apart: Savitri's temple stands on Ratnagiri hill behind the Brahma temple, and Gayatri's on a lower hill on the other side of the lake. The curse is told as the reason Brahma has almost no temple but this one. Pilgrims bathe in the lake at Karttika full moon.
What is different here:
The curse becomes "worshipped nowhere but Pushkar"; Gayatri is a Gurjar girl; the two hill temples carry the quarrel into the landscape.
