And then... you are free ! You don't carry the burden of begrudge. You are not occupied with thoughts about the matter. Oh, yes, these thoughts !!... They range from revenge ( sweet or bitter) all the way to self-doubt (and further more to self -hatred).
These thoughts that pester in you... like brewed yeast.
Until you wake up one morning ( or night) to the sound of the voice that whispers ( or shouts): "ENOUGH"! No one in the world should hold this power over you. The power that you give to others so freely, unaware that you do.
Forgive them - because you deserve to be free !
