"Everything I love, I will lose. That's the harsh truth. You either have to shut down your heart - and miss the love that is around you - or wrestle with that truth and come out the other end. There is indeed such a thing as joyful sorrow. The work of the mature person is to carry grief in one hand and gratitude in the other and to be stretched large by them."
My favorite magazine is called The Sun - it's a literary treasure that publishes interviews as well as fiction, nonfiction and poetry. The October issue happens to be on grief, with an interview of psychotherapist Francis Weller. The quote above belongs to him.
