Chanakya had personally supervised the creation of an entire army of such maidens. His secret service would identify young and nubile girls whose horoscopes foretold of widowhood. These beautiful damsels would be sequestered at an early age and fed a variety of poisons in graduated doses, making them immune to their ruinous effects. By the time each of Chanakya’s vishakanyas reached puberty, they were utterly toxic. A simple kiss with an infinitesimal exchange of saliva was lethal enough to kill the strongest bull of a man.
