All religions try to benefit people, with the same basic message of the need for love and compassion, for justice and honesty, for contentment. So merely changing formal religious affiliations will often not help much. On the other hand, in pluralistic, democratic societies, there is the freedom to adopt the religion of your choice. This is good. This lets curious people like you run around on the loose!
I think when tragic things happen it is on surface. It is like the ocean. One the surface a waves and sometimes the wave is very serious and strong. But it comes and goes, comes and goes, and underneath, the ocean always remains calm. Tibetans have a saying: "If bad news comes to you listen here" (points to the right ear) "and let it our here" (points to the left ear).
When the days become longer and there is more sunshine, the grass becomes fresh and, consequently, we feel very happy. On the other hand, in autumn, one leaf falls down and another leaf falls down. The beautiful plants become as if dead and we do not feel very happy. Why? I think it is because deep down our human nature likes construction, and does not like destruction. Naturally, every action which is destructive is against human nature. Constructiveness is the human way. Therefore, I think that in terms of basic human feeling, violence is not good. Non-violence is the only way.
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.
I always emphasize that it is much safer and better to keep one's own religious faith. The other major religions are thousands of years old and have long traditions.
I always tell my Western friends that it is best to keep your own tradition. Changing religion is not easy and sometimes causes confusion. You must value your tradition and honor your own religion.
