I charge you all that each one of you concentrate all the thoughts of your heart on love and unity. When a thought of war comes, oppose it by a stronger thought of peace. A thought of hatred must be destroyed by a more powerful thought of love. Thoughts of war bring destruction to all harmony, well-being, restfulness and contentment … Thoughts of love are constructive of brotherhood, peace, friendship, and happiness.

In reality war is continuous. The moral effect of the expenditures of these colossal sums of money for military purposes is just as deteriorating as the actual war and its train of dreadful carnage and horrors. The ideal and moral forces of the contending parties become barbaric and bestial, the spiritual powers are stunted and the laws of divine civilization are disregarded. Such a financial drain ossifies the veins and muscles of the body-politic, and congeals the delicate sensibilities of the spirit.

There is not the least doubt that the nation or the government which puts forward and extraordinary effort in the promotion of Universal Peace will be enriched with Divine Confirmation and will be the object of honor and respect among all the inhabitants of the earth.
