Yes, there is a Nirvanah; it is leading your sheep to a green pasture, and in putting your child to sleep, and in writing the last line of your poem
[Our family is] a wonderfully messy arrangement, in which relationships overlap, underlie, support, and oppose one another. It didn't always come together easily nor does it always stay together easily. It's known very good times and very bad ones. It has held together, often out of shared memories and hopes, sometimes out of the lure of my sisters' cooking, and sometimes out of sheer stubbornness. And like the world itself, our family is renewed by each baby.
