The well of experience.
Our inner resources are bottomless - like the spirit itself. Next time you need to draw upon some aspect of your inner strength - perhaps your courage, patience or tolerance - imagine lowering a bucket into a well. No matter how much energy you draw from this source, there will always be vast reserves still left in place. As you raise your bucket, make a vow to use this energy wisely and lovingly.
