We have all been hurt by someone that we love. Sometimes the hurt is so extreme that we find it hard to forgive. We may say that we forgive but the next time you find yourself in a similar situation with this person, the anger and pain of the previous hurt compiles on top of the current hurt until there is an underlying seething that is always ready to surface, sometimes at the most minor incident.
How can we get past these feelings? Forgiveness. I don't mean the kind of forgiveness that someone says they are sorry and you say, "okay, I forgive you" and you move on but place that hurt in a folder to take out next time it happens. True forgiveness comes from not just letting go of the pain but also letting go of the incident that caused the pain. Not putting it into a folder to save for the next time.
The key to forgiveness is in understanding the intentions of the other person. You can only do this through Agape - unconditional love. Agape is the purist kind of love because it transcends the ego.
When you love someone unconditionally, you can easily forgive because you can see through the persona of the person into their core. You can see their heart. When you can see someones heart then you know their intentions. If there is no malice with intent to hurt you then how can you not forgive?
Love has many flavors but love in the purist form is unconditional. It will not shield you from being hurt but it will allow you to forgive and continue loving. Love is the most precious and valuable experience a human can have. All the riches in the world cannot buy love.
