Famous quotes containing the words special and/or rays:

    “Our normal waking consciousness, rational consciousness as we call it, is but one special type of consciousness, whilst all about it, parted from it by the filmiest of screens, there lie potential forms of consciousness entirely different.”
    —William James (1842–1910)

    “Thus while I sit and sigh the day
    With all his borrow’d lights away,
    Till night’s black wings do overtake me,
    Thinking on thee, thy beauties then,
    As sudden lights do sleepy men,
    So they by their bright rays awake me.”
    —Sir John Suckling (1609–1642)
