...Today, the most important affair and greatest hope is the unity and concord of the Friends. In every city where the Friends are united, spirituality and illumination is manifest and apparent with infinite power and strength; but where there is a lack of the warmth of love, every one becomes withered, cold, unhappy and deprived. Therefore, endeavor ye with all your heart and soul so that union and concord may be increased, the Word of God promoted and the lights of unity be spread. Convey on behalf of ‘Abdu’l-Baha the wonderful Abha Greeting to all the Friends of that Spiritual Assembly.
(‘Abdu’l-Baha, extract from a Tablet, Star of the West, vol. 1, no. 10, September 8, 1910)
