True peace is not a forced truce, not a homogenization of differences, not a common ground that abandons our home territories.
True peace is the oneness that sprouts from diversity, from a panorama of colors, strokes and textures. From the harmony of many instruments each playing a unique part, not one overlapping the other's kingdom by even the breadth of a hair. There, in the most delightful beauty of this world, there shines G‑d's most profound oneness.
Those who attempt to blur those borders, they are unwittingly destroying the world. Beginning with the crucial border between man and woman—for this is the beginning of all diversity, the sharpest focus of G‑d's oneness, shining intensely upon His precious world.
—Likkutei Sichot, volume 18, Korach 3
Based on letters and talks of the Rebbe, Rabbi M. M. Schneerson
