Human
brotherhood and dependence exist because mutual helpfulness and cooperation are
the two necessary principles underlying human welfare. This is the physical
relationship of mankind. There is another brotherhood—the spiritual—which is
higher, holier and superior to all others. It is heavenly; it emanates from the
breaths of the Holy Spirit and the effulgence of merciful attributes; it is
founded upon spiritual susceptibilities. This brotherhood is established by the
Manifestations of the Holy One.
