Concentrate on what is essential, nothing lasts.
As I sat in Colchester Castle Park I noticed a 3-year-old boy and his mother passing by. The boy in delight pointed to a spiderweb, but his mother busy with a smartphone ignored the boy. Many times the boy mentioned the spiderweb, and each time the mother ignored him.
Forty years from now I doubt mother or son will remember this spiderweb incident that I record. I doubt even if the mother will remember what it was she was doing on her smartphone at the time. It could be that the mother was dealing with an important matter on her smartphone when her son drew her attention to the spiderweb, but often as is the case with smartphones it was a trivial issue. What matters was an opportunity lost where mother and son could have shared a magical moment of delight in a spiderweb, a moment that could have stayed with the mother as a magical memory into old age.
Impermanence is a fact of life, nothing lasts, thus the smallest moments shared like between that mother and son become like treasure, sadly wasted to worthless distractions such as Facebook updates via smartphone.
