Z'ev Ben Shimon Halevi said this quote

“ Everyone is searching for something. Some people pursue security, others pleasure or power. Yet others look for dreams, or they know not what. There are, however, those who know what they seek but cannot find it in the natural world. For these searchers many clues have been laid out by those who have gone before. The traces are everywhere, although only those with eyes to see or ears to hear perceive them. When the significance of these signs is seriously acted upon, Providence opens a door out of the natural into the supernatural to reveal a ladder from the transient to the Eternal. He who dares the ascent enters the Way of Kabbalah. ”
