If a harmonious relationship is established amongst societies and religious beliefs in today's multi-ethnic, multi-religious and multi-cultural world, then it will surely set a very good example for others.

Buddha was speaking about reality. Reality may be one, in its deepest essence, but Buddha also stated that all propositions about reality are only contingent. Reality is devoid of any intrinsic identity that can be captured by any one single proposition - that is what Buddha meant by "voidness." Therefore, Buddhism strongly discourages blind faith and fanaticism.

We can reject everything else: religion, ideology, all received wisdom. But we cannot escape the necessity of love and compassion. This, then, is my true religion, my simple faith. In this sense, there is no need for temple or church, for mosque or synagogue, no need for complicated philosophy, doctrine, or dogma. Our own heart, our own mind, is the temple. The doctrine is compassion. Love for others and respect for their rights and dignity, no matter who or what they are: ultimately these are all we need.

Genuine harmony must come from the heart. It cannot come from the barrel of a gun.

Meet hostility and suspicion with kindness. Helping others out of love is always the best option.

If you focus only on yourself and neglect others, you will lose; but you will gain if you value others as much as you cherish yourself.

Basically, the Buddhist attitude is that you should not accept certain things through sheer faith. And for that you need a skeptical attitude. Buddha himself made this clear to his followers. He said you should not accept those things I taught out of respect for me, but rather through investigation by yourself.
