"The Holy Spirit or the Shechinah, as we have already observed, is symbolized by the letter 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 Shin into the midst of the elemental name of Tetragrammaton, thus forming a new word 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."
