When we are young and again when we are old, we depend heavily on the affection of others. Between these stages we usually feel that we can do everything without help from others and that other people's affection is simply not important. But at this stage I think it is very important to keep deep human affection.
We can't blame the entire Muslim society because of the mischievous acts of a few individuals. Therefore, at the general public level we must cultivate the notion of not just one religion, one truth, but pluralism and many truths. We can change the atmosphere, and we can modify certain ways of thinking.
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.
Of course, there are different truths on different levels. Things are true relative to other things; "long" and "short" relate to each other, "high" and "low," and so on. But is there any absolute truth? Something self-sufficient, independently true in itself? I don't think so.
Our world and our lives have become increasingly interdependent, so when our neighbour is harmed, it affects us too. Therefore we have to abandon outdated notions of 'them' and 'us' and think of our world much more in terms of a great 'US', a greater human family.
