Cursing is a boomerang. If I will evil towards someone else, that evil becomes visible in me. It is an extreme way of being forensic, toward myself, as well as toward whoever outrages me. To avoid contaminating myself and everybody around me, I must work through the anger and the hurt feelings and the demands for absolute justice to a desire for healing. Healing for myself, and my anger, first, because until I am at least in the process of healing, I cannot heal; and then healing for those who have hurt or betrayed me, and those I have hurt and betrayed.
— Madeleine L’Engle, A Stone for a Pillow, quoted in Glimpses of Grace, compiled by Carole F. Chase
