Examples of sidereal in a Sentence

  1. Philipus Aureolus Paracelsus:

    Thoughts give birth to a creative force that is neither elemental nor sidereal. Thoughts create a new heaven, a new firmament, a new source of energy, from which new arts flow. When a man undertakes to create something, he establishes a new heaven, as it were and from it the work that he desires to create flows into him. For such is the immensity of man that he is greater than heaven and earth.
