Why Forgiveness For Everyone?

Few days back I was playing with Vaed, and we both were very happy about the time we were spending together and most important thing is that I knew it then. He started playing with my cellphone, and suddenly out of excitment hit my head with the cellphone a couple of times. It was very hard and it hurt me very much, but I was not angry or unhappy at all about this gesture from Vaed, and I put my hand on my head and started explaining him that he should not do this, it hurts dadda... etc.

After a while I started thinking, would it have been done by someone else, I would have reacted in a different way. Really, I forgave him right at that time or even better that I did not feel bad about it. There are couple of reasons I did not feel bad about it, one is my love for him and the other is that I am very well aware that he doesn't know that it hurts me when he hits me. He did not really do it intentionally and it is these experiences that will really make him understand and learn things.

They say that we (souls) come to physical life/body on earth to learn things that we decided to, or we need to from a lifetime. When we are in physical form, we don't really know that we decided to live through some experiences and others are helping us. We don't know that others don't really know that they are probably accumulating some Karmas by hurting us in a way, we are ignorant of these facts. Would we know these facts, we would not do such things. If so, and if we believe in this theory (till we personally experience it), why can't we forgive others, that do bad to us, from the bottom of our heart (like I did to Vaed)?

Eventually this is going to help us, since it will save us from accumulating a Karma and we will not need to come back to live through the experience where we hurt that other one and be in opposite roles.

Forgiveness For Every One!!! To help yourself!!!
