Brahma's Sacrifice at the Confluence of Ganga and Yamuna
Where the Ganga meets the Yamuna, the waters themselves are sacred — visited by sages, supreme among purifying places. But the place did not become famous on its own. In earlier times, Brahma performed a sacrifice there, and the confluence has been known as Prayaga ever since.
There is a confluence of the Ganga and the Yamuna, renowned in the world. It is pure and sacred, supreme among purifying places, and visited by the sages.
In earlier times, the grandfather — Brahma, the soul of all beings — performed a sacrifice there. That is the reason it has become famous as Prayaga.
The place where two sacred rivers meet, where the waters of the Ganga and the Yamuna flow together into one stream — this is where the creator himself once sat, where the fire of sacrifice burned on the bank, where the gods themselves must have gathered to witness. The land remembers. The waters remember. And those who come to Prayaga come to a place that was consecrated before any human temple was built, before any human king ruled, when the world was still young and the gods walked openly upon the earth. Aranyaka Parva, Chapter 382
