Peace is light whereas war is darkness.
When we consider outcomes in the world of existence we find that peace and fellowship are factors of upbuilding and betterment whereas war and strife are the causes of destruction and disintegration. All created things are expressions of the affinity and cohesion of elementary substances, and non-existence is the absence of their attraction and agreement. Various elements unite harmoniously in composition but when these elements become discordant, repelling each other, decomposition and non-existence result. Everything partakes of this nature and is subject to this principle, for the creative foundation in all its degrees and kingdoms is an expression or outcome of love. Consider the restlessness and agitation of the human world today because of war.
