It seems to me that one of the essential life skills is enjoying life itself. It is something we can learn, from being around other people who have mastered the art. We go with a friend to a museum, and after we have seen the exhibits we sit down with a coffee in the restaurant, and perhaps with our coffee we might have a piece of carrot cake. All small pleasures that we seek out, but there is a certain rhythm to it, a bonhomie.
Even when you do not seek them out, life places these things generously on our path. The scent of grass after the rains have passed, the glorious colours of a sunset, the pleasure of moving your body while bicycling. All you have to do is be present for them, maintain a kind of meditative awareness, and they come to visit you.
It becomes more difficult when we think of some of the greater pleasures. Our loved ones, children or parents or close spiritual friends, when they leave us because people do die, we feel the gaps they leave behind, and for weeks and months we feel as if something is missing, or that they could just come around the corner.
That is when we notice we have grown used to them, and our lives were shaped to fit their presence, like an old shoe around its masters foot. However much we try to hold their presence loosely, and not cling, in the end there is a period of adjustment to their absence which is inescapable.
