Silence.

I am the word that lovers leave unsaid,
    The eloquence of ardent lips grown mute,
The mourning mother's heart-cry for her dead,
    The flower of faith that grows to unseen fruit.

I am the speech of prophets when their eyes
    Behold some splendid vision of the soul;
The song of morning stars, the hills' replies,
    The far call of the immaterial pole.

And, since I must be mateless, I shall win
    One boon beyond the meed of common clay:
My life shall end where other lives begin,
    And live when other lives have passed away.
