I remember a song about how love hurts. It has been a long time since I have heard it, but I am sure there are a ton of songs with the same message about love and hurt and emotional pain.
It also seems, based on the many stories I have heard from folks, that love is like a homeopathic remedy. You take the substance in a different form and it will do two different things. It will reinstitute the feelings at multiple levels from the joy to the disappointment. It also works on the ethereal level where it unblocks blocked energy. So it does ease the pain since it was also the cause.
There are so many things in our lives that bring us both joy and pain. One goal of living is to expand the joy and diminish the pain. More often than not the pain is caused by not understanding self. We move into situations in search of the balm that will soothe the pain, and sometimes the cure is more painful than the original problem. But sometimes the pain leads to new levels of joy because something deep and fundamental has been understood.
Do not let the other end of love or hate manifest in whatever the situation may be. Always seek to understand the circumstances and your part in them. We are all 50% responsible for everything that occurs in our life.
Here is another thing about love and hate. When you are deep into either one, your eyes will well up with tears. That distorts your vision. Seek to maintain clarity so that hurtful and hateful things are never said. I know it is easier said than done, but so is living a loving life.
Love one another, because when you strip away the physical container we are all identical.
