You can’t see the wind, but you know it is there. It exists. You can’t see it with your eyes, but you feel it. You experience it. At times you can see its impact by the movement of the leaves in the tress, but still you cannot actually see the wind.
Much of life is that way. You must feel it and experience its impact…. not only observe it with your eyes to know that it is real.
