O Friends! It is the wish of ‘Abdu’l-Baha that the friends
may establish general unity ... We are all servants of one threshold,
attendants at one court, waves of one sea, drops of one stream, dust before one
door and plants of one garden. The beloved of God must be friendly, even with
strangers, and intimate even with outsiders. … There must be gatherings for
matters which concern the well being of men … which concern all in general and
not a particular number. 
- ‘Abdu’l-Baha  (From an early Tablet to the beloved of
God in Tehran; Baha’i News no. 48, February 1931)
