Translation:
At that time, all the persons assembled in the sacrificial arena — the priests, the chief of the sacrificial performance, and the brāhmaṇas and their wives — wondered where the darkness was coming from. Later they could understand that it was a dust storm, and all of them were full of anxiety.
