Our inner work is to tune our hearts and our senses to perceive the spiritual world says Michael Laitman in the poem Spiritual Wave. This is a lovingly crafted anthology comprised of Kabbalistic tales and allegories passed through Dr Michael Laitman, and his mentors Rav Baruch Ashlag (Rabash), and Rabash's father Rav Yehuda Ashlag. The desire of the Kabbalah student is to reach higher levels of spiritual attainment, yet it is difficult to imagine the sensations of the spiritual world. The verse in this reflective and insightful compilation gives the reader a glimpse into the essence of this elevated state of being. The poems herein are excerpts from letters and lessons given by these three, spiritual leaders. They offer inspiring and often amusing depictions of human nature that resonate with reader regardless of his/her level of study. Indeed, this book is a tool for any student seeking to find higher levels of spiritual attainment.
