Famous quotes containing the words occult and/or blood:

    The greatest delight which the fields and woods minister, is the suggestion of an occult relation between man and the vegetable. I am not alone and unacknowledged. They nod to me, and I to them.
    Ralph Waldo Emerson (1803–1882)

    I too have been in the underworld, as was Odysseus, and I will often be there again; not only sheep have I sacrificed so as to be able to speak with a few dead souls, but neither have I spared my own blood as well.
    Friedrich Nietzsche (1844–1900)
