It is not made up of a loose collection of segments. Unity is intrinsic and indivisible. Uniformity is an unnatural collection of many segments pushed together that may impose a strain on our fundamental unity, unless we are open and strong enough to allow room for the variance that is there. We are all children of our culture, and the accompanying diversity should not be a threat to anyone. Rather, diversity is a matter of beauty and complementary fulfillment.
Diversity means reciprocal enrichment.
But it requires mutual acceptance and understanding. Unity is both fragile and strong. Unity is fragile in that it will not survive compromises for the sake of convenience. It cannot survive adjustments of principles to accommodate the secular society. If that happens, fragmentation inevitably sets in.
