MOST visitors at the Bharatiya Janata Party (BJP) headquarters at New Delhi's Ashoka Road don't stop by the kitchen garden that lies to the back of the outhouse. Even if they did, they wouldn't discover a large hollow metallic sphere, for it's cleverly buried in a silo deep beneath the onion patch. Two-thirds of the sphere's surface is permanently painted saffron with beautiful images of a lotus, a golden chariot, the rubble of a mosque and the slogan "Jai Shri Ram". The remaining third is an interchangeable panel, which can be coloured according to the mood of the allies of the time. In a top secret operation conducted a few days ago, the smaller panel was painted bright red with a splendid hammer and sickle prominently displayed amidst images of Marx, Lenin, Stalin and Mao.
