You can hear it best when your heart longs for a place to rest. It will happen at the most inopportune moments, too - those times when you are hip deep in shopping, errands, planning that grand event, or... then. now...
You know this because you have heard the quiet call. You have longed for that rest.
Shhhh. Stop what you are doing. I give you permission - no, I encourage you! Go sit down in that favorite place you have, close your eyes - just for a few minutes. Rest and be still. You know you would tell me to do the same thing - so go do this for yourself.
