As we cross into the twenty-first century, it is clear humanity has entered an unprecedented global age. This global age of course has been emerging over millennia, but we now face a range of global crises that call for new ways of thinking and a new kind of consciousness to get to the source of the challenges. A number of initiatives have emerged which center on the collective wisdom of the ages—an emergent global wisdom that resonates across our diverse worldviews and traditions. In this context, Adi Da’s book Not-Two Is Peace taps this global wisdom. And the title of the book is right on the mark. He has said the real (even genetic) situation of the human species is prior unity, and peace requires that prior unity be the “working-presumption” of humankind. This simple and powerful principle reflects a consensus truth of global wisdom that there is That Which is First—an ultimate, unifying, infinite Force (whether we call it Tao, Aum, Brahman, Yahweh, Allah, Energy, Buddha Nature, Sunyata . . . ) that is the ground and source of all life, all existence, all worldviews, religions, cultures, forms of life. This is “Prior Unity,” and the collective wisdom of humanity has urged that unless and until humans center our lives in this Unifying Principle and Holistic Unified Field, we are not sustainable and we cannot flourish, individually and collectively. And we will not realize true peace. The narrative of Adi Da’s book is simple, powerful, accessible, and compassionate. And his message, grounded in global wisdom, is urgent and timely--he suggests that former ways of seeking peace have not worked and cannot work. Instead, we must mature and advance to a new form of consciousness that is grounded in “Prior Unity,” wherein we find our common ground, mature as humans, and touch the sacred space of true peace—hence “Not-Two Is Peace.” Adi Da recognizes that the wisdom of the ages--the awakening of this integral consciousness—calls for a radical networking from the heart and mind and urges that we form a Global Cooperative Forum to facilitate our transition to a true global culture of peace. So there is a powerful diagnosis and prescription for our human sustainability. This important book should be read carefully and put into practice by all global citizens.
