Women Who Run With the Wolves. Midwives of the Soul by Clarissa Pinkola Estés

 The doors to the world of the wild Self are few
but precious.
If you have a deep scar, that is a door.
If you have an old, old story,
that is a door.
If you love the sky and the water so much you almost cannot bear it,
that is a door.
If you yearn for a deeper life, a full life, a sane life,
that is a door.
