We encourage interested Baha'is to learn Esperanto

We feel that, within the framework of their efforts for the promotion of peace, the Bahá'ís of Europe would do well to increase their collaboration with the Esperanto Movement, and we encourage Bahá'ís who feel the urge to assist in this area, to learn Esperanto and take an active part in the activities of the Movement. As you know, although both 'Abdu'l-Bahá and Shoghi Effendi have made it clear that it is by no means certain that Esperanto will be chosen as the international auxiliary language of the world, 'Abdu'l-Bahá encouraged the friends in the east and the west to learn it as a practical step in the promotion of the concept of the adoption of an international auxiliary language to break down the barriers to understanding between peoples.
