“The current ideology of religious harmony emphasizes similarity—different religions are harmonious because they say the same thing; The older doctrine of multiple paths lays stress on their diversity—these paths are valid because they serve genuine different needs and answer to different natures. In short, they serve humanity not by being the same but by being different.”

Nobel lecture (2005)
Context: My sister-in-law works for a group that supports orphanages in Cairo. She and her colleagues take care of children left behind by circumstances beyond their control. They feed these children, clothe them and teach them to read.
At the International Atomic Energy Agency, my colleagues and I work to keep nuclear materials out of the reach of extremist groups. We inspect nuclear facilities all over the world, to be sure that peaceful nuclear activities are not being used as a cloak for weapons programmes.
My sister-in-law and I are working towards the same goal, through different paths: the security of the human family.

Context: We all have the same God, we just serve him differently. Rivers, lakes, ponds, streams, oceans all have different names, but they all contain water. So do religions have different names, and they all contain truth, expressed in different ways forms and times. It doesn't matter whether you're a Muslim, a Christian, or a Jew. When you believe in God, you should believe that all people are part of one family. If you love God, you can't love only some of his children.
