This is the tenth and final book of the 10-volume Mesorah Matrix series and is titled: V'shamru. Mesorah Matrix is a major - and potentially landmark - intellectual- spiritual-philosophical endeavor. The entire 10-volume series is now available - each on a very focused Jewish theme - under the Mesorah Matrix umbrella. Over 150 leading authors/essayists globally have been involved in the decade-spanning project. The focused-purpose and raison d'etre of the series is to more fully draw-out the spiritual and transcendent embedded within Judaism. These are sometimes referred-to as Elyonoth or "Higher-Sphere" themes. The intent of the quite- unique 10-volume series is to be "transformational." There are a total of two Senior Editors, each responsible for multiple books/themes. The Editor-in-Chief of the over-all series is David Birnbaum of Manhattan, author of the Summa Metaphysica philosophy series. Mesorah Matrix, in turn, is under the greater umbrella of New Paradigm Matrix Publishing which exclusively publishes "new paradigm" works - in metaphysics, philosophy, history and now, spirituality. Works by New Paradigm Matrix are Course Texts at major universities around-the-world. For Tikkun Olam, Senior Editor Martin S.
