Peace is the most covetable possession on the earth. It is the greatest treasure in all the universe. Peace is the most important and indispensable factor for all growth and development. It is in the tranquility and quiet of the night that the seed slowly sprouts from under the soil. The bud opens in the depth of the most silent hours. So also, in a state of peace and love, people evolve, grow in their distinctive culture, and develop perfect civilization.
