Perhaps it's possible to forgive in one grand swoop, but I didn't experience it that way. I did it in bits and pieces. You forgive what you can, when you can. To forgive does not mean overlooking the offense and pretending it never happened. Forgiveness means releasing our rage and our need to retaliate, no longer dwelling on the offense, the offender, and the suffering, and rising to a higher love. It is an act of letting go so that we can go on.
Since love and truth are the cornerstones of life and since they are but other names for praise and thanksgiving, it follows that praise and thanksgiving are important components of prayer. This is because prayer in its truest form is an alignment between the spiritual self of each of us with the spiritual Power that defies human understanding.
