The harder they strive to widen the scope of their knowledge, the better and more gratifying will be the result. Let the loved ones of God, whether young or old, whether male or female, each according to his capabilities, bestir themselves and spare no efforts to acquire the various current branches of knowledge, both spiritual and secular, and of the arts. Whensoever they gather in their meetings let their conversation be confined to learned subjects and to information on the knowledge of the day.
