Motherhood.

"The most difficult part of birth is the first year afterwards. It is the year of travail - when the soul of a woman must birth the mother inside her. The emotional labour pains of becoming a mother are far greater than the physical pangs of birth; these are the growing surges of your heart as it pushes out selfishness and fear and makes room for sacrifice and love. It is a private and silent birth of the soul, but it is no less holy than the event of childbirth, perhaps it is even more sacred." - Joy Kusek
