Chanakya devised an advanced system of human intelligence-gathering in which operatives wore saffron to deceive the masses. There were instances when, before sending in the army to raid a village, for example, these pseudo-renunciates were sent first to make a prophecy of doom to create chaos in the minds of the people and the enemy army. Often, such strategies were wonderfully effective since they resulted in surrender without a fight – saving countless innocent lives. Great care was taken to ensure that these saffron-clad people never went rogue, and were closely watched. These saffron-clad spies proved to be an effective weapon in the game of psychological warfare.
