O ye friends and the maid-servants of the Merciful, hearken to the counsels of Abdul-Baha. The world of matter is not worthy of consideration or indulgence therein. Soon the life of everything will come to an end, therefore you must endeavor to raise the banner of greatness in the unicolored universe of God, attract the splendors of the Sun of Truth, become the cause of the illumination of the realm of man, serve all humanity, spread the essential oneness, become the embodiment of Divine Mercy, the impersonation of the Gift of His Highness the Almighty, seek eternal life, and discover the majesty of the age-abiding sovereignty. 
(‘Abdu’l-Baha, from a Tablet; Star of the West, Vol. 1, no. 9, Aug. 20, 1910)
