[Cablegram, February 29, 1952]

During her Pilgrimage in 1953, Marguerite Sears, wife of Hand of the Cause of God William Sears, recorded Shoghi Effendi as having said...

A Hand is one who serves the Cause in an outstanding manner. The American Hands were appointed: Leroy for services rendered during the first seven year plan, Dorothy for her teaching ability, Millie and Fred for their great financial contributions during times of greatest need. They upheld the Faith. Roy was a saint, Sutherland for the Shrine of the Bab, Horace for his services in the Administration, Mrs. True for her Temple Service, Mason for continued service over a long time and for visiting all countries for the Faith.
In the future outstanding scientists, writers, leaders in their fields, will immediately become Hands as soon as they become Bahá'ís. It does not necessarily mean that they are greater spiritually, but they must become so."
