It is from this perspective that I welcome efforts being made in various parts of the world for better understanding among religions. The need for this is particularly urgent now. If all religions make the betterment of humanity their main concern, then they can easily work together in harmony for world peace. Interfaith understanding will bring about the unity necessary for all religions to work together. However, although this is indeed an important step, we must remember that there are no quick or easy solutions. We cannot hide the doctrinal differences that exist among various faiths, nor can we hope to replace the existing religions by a new universal belief. Each religion has its own distinctive contributions to make, and each in its own way is suitable to a particular group of people as they understand life. The world needs them all.
