H. P. Blavatsky

Tzure. Almost the same as the above: the prototype of the “Image” tzelem ; a Kabbalistic term used in reference to the so‐called creation of the divine and the human Adam, of which the Kabala (or Kabbalah) has four types, agreeing with the root‐races of men. The Jewish Occultists knew of no Adam and, refusing to recognise in the first human race Humanity with Its Adam, spoke only of “primordial sparks”.
