If my theory of relativity is proven successful, Germany will claim me as a German and France will declare me a citizen of the world. Should my theory prove untrue, France will say that I am a German, and Germany will declare that I am a Jew.
Before you can inspire with emotion, you must be swamped with it yourself. Before you can move their tears, your own must flow. To convince them, you must yourself, believe.
Whether you believe in God or not does not matter much, whether you believe in Buddha or not does not matter so much; as a Buddhist, whether you believe in reincarnation or not does not matter so much. You must lead a good life.
Because one believes in oneself, one doesn't try to convince. Because one is content with oneself, one doesn't need others' approval. Because one accepts oneself, the whole world accepts him or her.
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.
