December 27

Study the sciences, acquire more and more knowledge. Assuredly one may learn to the end of one’s life! Use your knowledge always for the benefit of others; so may war cease on the face of this beautiful earth, and a glorious edifice of peace and concord be raised. Strive that your high ideals may be realized in the Kingdom of God on earth, as they will be in Heaven. 
(‘Abdu’l-Baha, from a talk, Paris, October 26, 1911, ‘Paris Talks’)
