The literature on cultural migration is extensive. It usually concentrates on the consequences of moving to unfamiliar contexts and, often, the negative aspects of cross-cultural travel, using labels such ‘culture shock’ and detailing the impact of encountering so much that is new. The positive side of placing oneself in a new culture is mentioned less often, yet, for many cross-cultural travellers, observing and experiencing others’ ways is, on balance, more interesting than it is painful; it can prompt better understanding of one’s own assumptions and beliefs in the same way that the first astronauts to the moon looked back and saw the Earth as a blue sphere.
