God is omnipresent.
Yet it is difficult for us to see it in those who hurt us. We want to lash out at them. We find ourselves unable to forgive them.
Till the time we calm down to see God within those who hurt us, and to view them benevolently, we need to make a concerted effort to pull ourselves up from the negativity.
We need to have faith that God is just and merciful and that karma will catch up with those people.
Sometimes the effects of karma are worse than anything we could have wished on that person, making us sincerely pray for them, even as we are unable to forgive them.
