SB 8.18.21
tam narmadayas tata uttare baler
ya rtvijas te bhrgukaccha-samjñake
pravartayanto bhrgavah kratuttamam
vyacaksatarad uditam yatha ravim
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
While engaged in performing the sacrifice in the field known as Bhrgukaccha, on the northern bank of the Narmada River, the brahminical priests, the descendants of Bhrgu, saw Vamanadeva to be like the sun rising nearby.
