Humanity must suffer very much before it comes to an understanding of the advantage of unity. Most destructive forces have been directed for the purpose of obscuring the embryos of unification. Each unifying agent is subject to personal danger. Each peace-maker is disparaged. Each worker is ridiculed. Each builder is called madman. Thus the servants of dissolution try to drive from the face of the Earth the Banner of Enlightenment. Work is impossible amid enmities. Construction is inconceivable amid explosions of hatred. Fellowship is battling with man-hatred. Let us keep in memory these old Covenants.
(Nicholas Roerich, born on 9 October 1874, Sun and Moon in Libra, Russian mystic and painter)
