This meditation has appeared in a number of places. This one is taken from The Millionth Circle - How to Change Ourselves and the World by Jean Shinoda Bolen, M.D., with her permission.
C O M M I T M E N T
Until one is committed, there is hesitancy,
the chance to draw back, always ineffectiveness,
concerning all acts of initiative (and creation).
The moment one definitely commits oneself,
then Providence moves, too.
A whole stream of events issues from the decision.
Whatever you can do or dream you can,
Begin it.
Boldness has genius, power and magic in it.
Begin it now.
- W.H. Murray,
