“All phenomena are interdependent. When we think of a speck of dust, a flower, or a human being, our thinking cannot break loose from the idea of unity, of one, of calculation. We see a line drawn between one and many, one and not one. But if we truly realize the interdependent nature of the dust, the flower, and the human being, we see that unity cannot exist without diversity. Unity and diversity interpenetrate each other freely. Unity is diversity, and diversity is unity. This is the principle of interbeing.”

Saying 368
Râmakrishna : His Life and Sayings (1898)

Address before the Indian Council of World Affairs, New Delhi, India, April 5, 1956, as quoted in Walter P Reuther: Selected Papers (1961), by Henry M. Christman, p. 133 If the peoples of great nations can work, sacrifice, fight, and die together because they share common fears and common hatreds in war, why can we not find a way to tap the great spiritual reservoir that lies deep within each of us and get people and nations working, sacrificing, and building together in peacetime because they share common hopes and common aspirations.

Sādhanā : The Realisation of Life http://www.spiritualbee.com/spiritual-book-by-tagore/ (1916)
Context: Though the West has accepted as its teacher him who boldly proclaimed his oneness with his Father, and who exhorted his followers to be perfect as God, it has never been reconciled to this idea of our unity with the infinite being. It condemns, as a piece of blasphemy, any implication of man's becoming God. This is certainly not the idea that Christ preached, nor perhaps the idea of the Christian mystics, but this seems to be the idea that has become popular in the Christian west.
But the highest wisdom in the East holds that it is not the function of our soul to gain God, to utilise him for any special material purpose. All that we can ever aspire to is to become more and more one with God. In the region of nature, which is the region of diversity, we grow by acquisition; in the spiritual world, which is the region of unity, we grow by losing ourselves, by uniting. Gaining a thing, as we have said, is by its nature partial, it is limited only to a particular want; but being is complete, it belongs to our wholeness, it springs not from any necessity but from our affinity with the infinite, which is the principle of perfection that we have in our soul.

Nobel Address (1991)
Context: Today, peace means the ascent from simple coexistence to cooperation and common creativity among countries and nations.
Peace is movement towards globality and universality of civilization. Never before has the idea that peace is indivisible been so true as it is now.
Peace is not unity in similarity but unity in diversity, in the comparison and conciliation of differences.
And, ideally, peace means the absence of violence. It is an ethical value.
