The power of appreciation comes through actions. Feeling gratitude creates a wonderful internal experience; expressing it allows us to feel the full bloom of appreciation. Most significant would be our willingness on a moment-to-moment basis to find some aspect of every person and event to appreciate and then find a tangible way to express our gratitude.
We must develop and maintain the capacity to forgive. The one who is devoid of the power to forgive is devoid of the power to love. Forgiveness is not an occasional act, it is a permanent attitude.
