As material and physical sciences ...

As material and physical sciences are taught here and are constantly unfolding in wider vistas of attainment, I am hopeful that spiritual development may also follow and keep pace with these outer advantages. As material knowledge is illuminating those within the walls of this great temple of learning, so also may the light of the spirit, the inner and divine light of the real philosophy glorify this institution. The most important principle of divine philosophy is the oneness of the world of humanity, the unity of mankind, the bond conjoining East and West, the tie of love which blends human hearts.
Therefore, it is our duty to put forth our greatest efforts and summon all our energies in order that the bonds of unity and accord may be established among mankind. For thousands of years we have had bloodshed and strife. It is enough; it is sufficient. Now is the time to associate together in love and harmony. For thousands of years we have tried the sword and warfare; let mankind for a time at least live in peace.
