تحفة النظار في غرايب الامصار وعجايب الاسفار 17.2.5

17.2.5

I sent her, however, to the Vizier, who ordered four large water vessels to be filled with water, and tied to her. She was then thrown into the great river (the Jumna). She did not sink in the water, but remained unhurt: so they knew that she was a Goftar. The Vizier then ordered her to be burnt, which was done; and the people distributed her ashes among themselves, believing that if any one would fumigate himself with them, he would be secure from the fascinations of a Goftar for that year. But if she had sunk, they would have taken her out of the water; for then they would have known that she was not a Goftar. I was once in the presence of the Emperor of Hindustan, when two of these Jogees, wrapt up in cloaks, with their heads covered (for they take out all their hairs, both of their heads and arm-pits, with powder), came in.
