‘Most of us recognise impermanence at an intellectual level. But we still become upset when one of our possessions breaks, when a relationship ends, or when we notice that we are growing older. We act – and in our heart of hearts we think – as though all things were unchangeable and permanent. And the tension created by trying to maintain an attitude which is so profoundly at odds with reality introduces a jarring and irritating quality into our everyday experience, because the real world is constantly slapping us in the face whenever it fails to match up to our illusions.’ Chris Pauling
