The word 'expenditure' is usually associated with cost, and thus with loss. But there are losses, which lighten the load I am to myself. The most worthwhile payment you can make in life is that of paying attention. The advantaged child is not the one with better shoes or wealthier parents, but the one who watches and listens closely in class. His exam preparations are minimal compared to the distracted others.
We are seven-tenths water and when we open our consciousness to allow inflow of information, intelligence, wisdom, perception, then that water organises an organic library, in our cells, of sensory experience, which we usually call memory. The attentive person allows themselves to be elementally altered by what is given them by the environment. I lose myself into the things I pay attention to, and so I become a kind of foreign exchange teller, a currency converter, if you like - whereby the words the most beautiful expenditure etch themselves (who knows from where?) into my thought to wake me, and I attend to this foreign thought, permit it to move my body to get up with the dawn, to take a photograph of the tree and mountain silhouette and pale morning star, and then my pen, so you, in turn, may have this, to give your time to, read and ponder.
