Leaves of Grass (Unfolded out of the Folds) Walt Whitman

Unfolded out of the folds of the woman man comes unfolded, and is
        always to come unfolded,
Unfolded only out of the superbest woman of the earth is to come the
        superbest man of the earth,
Unfolded out of the friendliest woman is to come the friendliest man,
Unfolded only out of the perfect body of a woman can a man be
        form'd of perfect body,
Unfolded only out of the inimitable poems of woman can come the
        poems of man, (only thence have my poems come;)
Unfolded out of the strong and arrogant woman I love, only thence
        can appear the strong and arrogant man I love,
Unfolded by brawny embraces from the well-muscled woman
        love, only thence come the brawny embraces of the man,
Unfolded out of the folds of the woman's brain come all the folds
        of the man's brain, duly obedient,
Unfolded out of the justice of the woman all justice is unfolded,
Unfolded out of the sympathy of the woman is all sympathy;
A man is a great thing upon the earth and through eternity, but
        every of the greatness of man is unfolded out of woman;
First the man is shaped in the woman, he can then be shaped in himself.
