“Just for today,” the words of Michao Usui, founder of Reiki.
And another of my personal favorites, that prayer of St. Francis of Assissi:
“Lord, make me an instrument of thy peace. Where there is hatred, let me sow love. Where there is injury, let me sow pardon. Where there is doubt, let me sow faith. Where there is despair, let me sow hope. Where there is darkness, let me sow light. Where there is sadness, let me sow joy. O Divine Master, grant that I may not so much seek to be consoled as to console, to be understood as to understand, to be loved as to love. For it is in giving that we receive. It is in pardoning that we are pardoned. It is in dying that we are born to eternal life.”
