Covering the whole land of Gokula with particles of dust, that demon, acting as a strong whirlwind, covered everyone’s vision and began vibrating everywhere with a greatly fearful sound.

Trnavartasura assumed the form of a whirlwind and covered with a dust storm the whole tract of land known as Gokula, so that no one could see even the nearest thing.
