There goes a Chanakya quote: Prakalp ki safalta uski gopniyata par nirbhar karti hai aur woh gopniya tab tak rahti hai jab tak chaar kaano tak seemit ho. That is, a project’s success depends upon its secrecy and it remains a secret only if it is restricted to four ears (between two persons). This advice from the 4th-century BC philosopher-jurist’s Arthashastra is often served to BJP workers by the party’s president Amit Shah, even as he himself revels in the art of inscrutability.
