From letters written on behalf of the Guardian

Shoghi Effendi feels that the real purpose of these Summer Schools is to deepen the knowledge of the friends. Lectures are very essential for they give a wonderful picture of the subject-matter. But it is not sufficient to have a picture; the friends should deepen their knowledge and this can be achieved if together with the lectures there are study classes and seminar work carried on by the same lecturer.

The world is undoubtedly facing a great crisis and the social, economic and political conditions are becoming daily more complex. Should the friends desire to take the lead in reforming the world, they should start by educating themselves and understand what the troubles and problems really are which baffle the mind of man. It is in these Summer Schools that this training should be provided for the friends.
