This is the time of teaching. All the believers must unloose the tongue of teaching the Cause of God. For teaching is the cause of the guidance of all the inhabitants of the earth; teaching is the means of the illumination of mankind; teaching is conducive to the enlightenment of the world of humanity; teaching is promotive of the confirmations of the Breaths of the Holy Spirit. This is the most great affair! 
- ‘Abdu’l-Baha  (From a Tablet, Star of the West, vol. 5, no. 9, August 20, 1914)
