Doroteo Juarez used to drink a lot of mescal. One evening he saw a giant nagual in shape of dragon. The nagual asked for a drink, and Doroteo got so frightened that he promised to the Virgin of Guadalupe to stop drinking if she chase the nagual away. The nagual disappeared like smoke in the air. The Doroteo’s wife thanks the Virgin because her husband doesn’t drink anymore and his life is happier now.
