“Equipped with the instrument of birth control, the mother regains not only mastery of her procreative function, but an immeasurably increased sense of power over life itself.... A whole sphere of life -- the sexual -- ­is elevated from the level of the purely instinctive and fortuitous and submitted to intelligent direction. Mystery and ignorance are banished. Married love is enriched and greatly reinforced by completely fulfilled sexual communion which has been emancipated of the destructive restrictions and mutilations of unexpressed fears. And so between husband and wife mental and spiritual bonds are strengthened and vitalized.”
