"The Holy Spirit or the Shechinah, as we have already observed, is symbolized by the letter ש Shin. When, therefore, a man has invoked the Spiritual Self, his Holy Guardian Angel, and attained to His Knowledge and Conversation, the process is described as the descent of the letter ש Shin into the midst of the elemental name of יהוה Tetragrammaton, thus forming a new word יהשוה Yeheshua, the Pentagrammaton, the symbol of a new being, the Adept or Tsaddik in whom the birth of Spirit has equilibrized the base and unredeemed elements of matter."
