Think about it. All the precious things in life, are for a season.
Once we are conscious of the uniqueness of every instant, every situation, we will eventually appreciate it more... That's why we like so much shooting stars, isn't it? They are not better than the millennial stars hanging around, it is our perception of them that gives them a different value.
Because of the fear of losing, losing anything good, beneficial or appreciated, we humans are tempted to try to control. Control relationships, control security, control life itself, in the attempt to prevent the pain and discomfort of loss. Do you relate to this?...
The truth is that, no matter how hard you work in keeping life together, there are things that will force us to let go of things we did not want to, or were not ready to... and, we have to accept that, the effort of control will not even help us to at least enjoy the gifts of the present reality —FREELY—, from the bottom of our soul, to enjoy what is in front of us, at the very moment of it, and live it—life—as it was meant to.
