He feels that, if your health is now sufficiently good for you to endure the rigours of life in Germany at the present time, it would certainly be rendering the Faith a great service for you to return to Berlin and inspire the believers there, and teach the Cause. In connection with the question you asked him about the advisability of putting on your house a name plate saying "Bahá'í Buro", this is something you must get permission for either from the Spiritual Assembly of Berlin (if it is functioning by the time you return) or the National Assembly.
He was very happy to hear Herr Lehne is now so active in serving the Cause in Berlin and planning a large public meeting. When you write to him please assure him of the Guardian's appreciation and his prayers on his behalf.
