The question is not, never, ever, whether or not we will be given challenges and limitations. We will.
The question is, how will we hold them, how will we be changed, how will they shape us, what will we bring to the healing of them, what, if anything will be born in its place.

As to the butterfly, it will stay as long as it feels peace. The. It will say farewell and be on its way. Meanwhile you shared peace and beauty.
