Today the world of humanity is in need of international unity and
conciliation. To establish these great fundamental principles a propelling
power is needed. It is self-evident that the unity of the human world and the
Most Great Peace cannot be accomplished through material means. They cannot be
established through political power, for the political interests of nations are
various and the policies of peoples are divergent and conflicting. They cannot
be founded through racial or patriotic power, for these are human powers,
selfish and weak. The very nature of racial differences and patriotic
prejudices prevents the realization of this unity and agreement. Therefore, it
is evidenced that the promotion of the oneness of the kingdom of humanity,
which is the essence of the teachings of all the Manifestations of God, is
impossible except through the divine power and breaths of the Holy Spirit.
Other powers are too weak and are incapable of accomplishing this.
