Although suffering is no laughing matter when we are going through it, when it reaches its end, we can often feel so grateful that we laugh and cry all at once. This is because suffering is often associated with a tremendous amount of pressure - either placed upon us by our own self, or placed upon us by our perception of what we consider to be external circumstances. The result can feel like being crushed by thousands of tons - an unbearable feeling of restriction and angst.
However, nothing of such intensity can or does last since every occurrence, incident or event has a beginning, middle and eventually an end and when the end comes and the pressure is lifted, the result is a sense of blissful relief that is so ecstatic that we might even flip out with the energetic release.
Often, when one has hit such a pocket of suffering, it can feel as if it will never end. However, it is at this most difficult of time, when we feel it the most intensely that is the 'darkness before the dawn', or the final moments of that chapter of your life; just before the suffering extinguishes itself and passes away. At that moment, our feelings miraculously change and we become free. What we must remind ourselves of, in these unbearable moments is that even events have a birth, a life and a death - albeit in your own sense of perception. The purpose is to push that perception to the limit so that it releases itself from your system.
And then - all of a sudden and out of the blue, it is gone- as if it never existed at all; and it might even be replaced by the most exquisite joy. When such a pressure is lifted we can laugh and laugh uncontrollably until there is no wind left in our body... And suddenly the suffering becomes beautiful and we feel so grateful for its lesson. It seems paradoxical I know, but when we are touched by true suffering, and we really let it in, all that is left when it has gone, is a gentle smile of gratitude and compassion...
That is the miracle of what it means to be Human.
