terrible, violent winds [blew], and the elephants of the quarters trumpeted.
Vyāsa said:
Seeing that great army arrive, trembling with fear,
they all fled from the gandharva city in the ten directions.
Abandoning the city, the king of the gandharvas went to Meru, O king.
Taking all those maidens endowed with youth, beauty, and nobility,
he then gave them to the merchants, O king,
according to the rite prescribed in the Vedas, and in the presence of the gods.
Having then given the portion of clarified butter to the gandharva, the cow-born ones
then gave the portion of clarified butter to the gods, the ancestors, the Sun, the Moon,
Yama, and Mṛtyu.
Having duly offered the portions of clarified butter, those of auspicious vows took [them as wives].
From then on, when a gandharva marriage takes place,
they thoroughly receive a portion of clarified butter from all sides even today.
Those thirty-six thousand youths whom they offered,
their sons and grandsons [numbered] in the hundreds and thousands.
Therefore all of them were indeed created for servitude.
