December 24

The first condition is absolute love and harmony amongst the members of the assembly. They must be wholly free from estrangement and must manifest in themselves the Unity of God, for they are the waves of one sea, the drops of one river, the stars of one heaven, the rays of one sun, the trees of one orchard, the flowers of one garden. Should harmony of thought and absolute unity be nonexistent, that gathering shall be dispersed and that assembly be brought to naught. 
- ‘Abdu’l-Baha  (‘Selections from the Writings of ‘Abdu’l-Baha’)
