Letting go does not mean not caring about things. It means caring about them in a flexible and wise way.
Peace requires us to surrender our illusions of control.
Without integrity and conscience we lose our freedom.
When we take the one seat on our meditation cushion we become our own monastery. We create the compassionate space that allows for the arising of all things: sorrows, loneliness, shame, desire, regret, frustration, happiness.
Weigh the true advantages of forgiveness and resentment to the heart. Then choose.
We each have been betrayed. Let yourself picture and remember the many ways this is true. Feel the sorrow you have carried from this past. Now sense that you can release this burden of pain by gradually extending forgiveness as your heart is ready.
