dadau pracim disam hotre
brahmane daksinam disam
adhvaryave praticim vai
udgatre uttaram disam
kasyapaya ca madhyatah
sadasyebhyas tatah param
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
After completing the sacrifice, Lord Parasurama gave the eastern direction to the hota as a gift, the south to the brahma, the west to the adhvaryu, the north to the udgata, and the four corners — northeast, southeast, northwest and southwest — to the other priests. He gave the middle to Kasyapa and the place known as Aryavarta to the upadrasta. Whatever remained he distributed among the sadasyas, the associate priests.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The tract of land in India between the Himalaya Mountains and the Vindhya Hills is called Aryavarta.
