…when this human body politic reaches a state of absolute
unity, the effulgence of the eternal Sun will make its fullest light and heat
manifest. Therefore, we must not make distinctions between individual members
of the human family. We must not consider any soul as barren or deprived. Our
duty lies in educating souls so that the Sun of the bestowals of God shall
become resplendent in them, and this is possible through the power of the
oneness of humanity. The more love is expressed among mankind and the stronger
the power of unity, the greater will be this reflection and revelation, for the
greatest bestowal of God is love. Love is the source of all the bestowals of
God. Until love takes possession of the heart, no other divine bounty can be
revealed in it.
