We had heard through various channels the wonderful way your children had grown to speak about the Cause in public. Shoghi Effendi's hope is that they will, the three of them, become able and devoted speakers on the Cause and subjects akin to it. To do this properly they will need a firm foundation of scientific and literary training which fortunately they are obtaining. It is just as important for the Bahá'í young boys and girls to become properly educated in colleges of high standing as it is to be spiritually developed. The mental as well as the spiritual side of the youth has to be developed before he can serve the Cause efficiently.
