Crossing the barrier is a gradual process. Studying Kabbalah with the goal of nearing the Creator’s attribute–the attribute of bestowal–enhances one’s keenness.  Increasingly subtler insights surface, pertaining to the reality in which one lives.  One begins to feel the operations at the “backstage” of matter, the forces that operate the visible, perceptible matter.Kabbalah Science and The Meaning of Life  page 97by Rav Michael Laitman I’ve always imagined that crossing the barrier into the spiritual realm was a sudden occurence, with an unmistakeable awareness of what has just happened, and suddenly I am confronted with this quotation today! What to make of it? Perhaps the awakening that you have crossed the barrier is sudden while the process was in fact a gradual one. Keep studying Kabbalah my friends!
