Courage: a quality of spirit that enables you to face danger or difficulty (as in finding a cache) without showing fear.
Heart: the central or innermost part of something or the courage to be willing to try something.
The previous cache at this location had a tendency to move; this one should avoid that. It may require courage and heart to step up to finding this one. SOooo...read the hints to make things easier for yourself - or take a courageous person with you.
I find that this Native American saying still applies to this cache:
Go Forward With Courage
When you are in doubt, be still, and wait;
when doubt no longer exists for you, then go forward with courage.
So long as mists envelop you, be still;
be still until the sunlight pours through and dispels the mists
-- as it surely will.
Then act with courage.
