If the soul wishes to share his life, she must pass through the death on the cross with him: like him she must crucify her own nature through a life of mortification and self-denial, and surrender herself to be crucified in suffering and death, as God may ordain or permit it. The more perfect this active and passive crucifixion may be, the more intimate will be the union with the crucified and therefore the richer the participation in the divine life.
Saint Teresa Benedicta of the Cross
