A spy, under the guise of a vintner, may, on the occasion of procession of gods, funeral rites, festivals, and other congregations of people, go to sell liquor and present the cowherds with some liquor mixed with the juice of the madana plant. Then others may fall upon the intoxicated cowherds (and carry off the cattle).
