A world upside down may do South Asia a lot of good. This is a place where a lot of not-so-nicethings are happening with no one able to do anything about it. Perhaps the sheer act of turning things topsy turvy on the map will help us right our collective bearings, and the way we think of our terrain, ourselves, and our neighbours.
Think of it this way: Pakistan has always thought of India – as the enemy to the east. Suddenly, north is south, east is west, and the enemy is just not there! This is just a taste of how things will change. In the Universe within which the earth spins, the North. Pole and the South Pole are equally important. But because the Northerners monopolised science, history, cartography and astronomy, we Southerners are relegated to the nether world. Actually, of course, there is no reason why what is presently North should monopolise the top of the page. Actually, there is no reason why the top of the page should necessarily be 'good', but let that be. If we cannot change the goody-goody image of top of page, for now we will simply change the configuration of what goes in there—we will turn the map downside up, reverse the text to be right side up, and sit back and watch the fun.
North is where good is supposedly located. The gory Aryans, say our Hindutva pals, came in from the north and colonised the Gangetic maidaan. The South was where the lumpen dark-skinned Dravidians were pushed towards. The Himalayan chain, marking off the northern edge of the Subcontinent, is seen to be the pure fount of all wisdom and dignity. North, after all, was where the rishis meditated where Kailash holds court as Meru, the centre of the universe. The north is where Shiva hung out and Indra reigned (if these are gods, why do we always speak about them in the past tense?). And the North northern Gangetic plains was where Prince (later King) Ram held court, and the South was where the demon king Rawan ranted and raved and incarcerated the kidnapped (fair-skinned) Sita.
For the writers and interpreters of South Asian mythology, North was Good, and South, passable. So much so that when the river turns north, called Uttar Bahini, that is where you locate your holiest spots. This point of view is ingrained into the secular mind as well, starting with the idea that the cardinal direction is north with reference to which everything is defined. As long we cannot changed this mindset, better to convert the map. Easier that way.
