The N.S.A. should, indeed, advise the believers to lessen their correspondence with the Guardian. But under no circumstances it can prevent them from writing to him. For this is a sacred right and a supreme privilege which every believer can rightly claim to possess, as through it alone he can get in direct touch with his Guardian. If individuals feel, after the advice of the N.S.A. to lessen correspondence, an inner urge to write to the Guardian they should not be prevented or discouraged.
