"Originally home meant the center of the world - not in the geographical, but in the ontological sense. Mircea Eliade has demonstrated how home was the place from which the world could be founded. A home was established, as he says, "at the heart of the real". In traditional societies, everything that made sense of the world was real; the surrounding chaos existed and was threatening, but it was threatening because it was unreal. Without a home at the centre of the real, one was not only shelterless, but also lost in non-being, in unreality. Without a home everything was fragmentation.
Home was the centre of the world because it was the place where a vertical line crossed with a horizontal one. The vertical line was a path leading upwards to the sky and downwards to the underworld. The horizontal line represented the traffic of the world, all the possible roads leading across the earth to other places. Thus, at home, one was nearest to the gods in the sky and to the dead in the underworld. This nearness promised access to both. And at the same time, one was at the starting point and, hopefully, the returning point of all terrestrial journeys.
The crossing of the two lines, the reassurance their intersection promises, was probably already there, in embryo, in the thinking and beliefs of nomadic people, but they carried the vertical line with them, as they might carry a tent pole. Perhaps at the end of this century of unprecedented transportation, vestiges of the reassurance still remain in the unarticulated feelings of many millions of displaced people.
Emigration does not only involve leaving behind, crossing water, living amongst strangers, but, also, undoing the very meaning of the world and - at its most extreme - abandoning oneself to the unreal which is the absurd."
