Thou hast written regarding thy meeting with... He hath
written that he desireth to teach thee one of the crafts and show thee
affection and consideration. We beseech God that this purpose may be attained,
and thou wilt learn such a skill, for according to the divine ordinances, every
person must acquire a craft.
(‘Abdu’l-Baha, The Compilation of Compilations
vol. I, The Arts)
