The Ho’oponopono Prayer could be exactly what you're looking for in your relationships -- with others, with the earth, with yourself.
There are four forces at work in this prayer: repentance, forgiveness, gratitude, and love. These are reflected in the four phrases that make up the prayer.
The phrases, which you can repeat in any order, silently to yourself or out loud, are:
I am sorry.
(Please) Forgive me.
Thank you.
I love you.
