In those days, the Persians cannot meet Rúhíyyih Khánum

In the afternoon when I was coming to the gardens I saw Shoghi Effendi. And I saw Rúhíyyih Khánum from the car. In those days, the Persians cannot meet Rúhíyyih Khánum according to the Persian custom, the man could not see unchadored women. So Shoghi Effendi respected Islam and the Persians could not see Rúhíyyih Khánum. But I saw Rúhíyyih Khánum. I went to Dr Hakim’s room which is in the gardens and saw Rúhíyyih Khánum for the first time but not face to face. The first time I saw Rúhíyyih Khánum in America was at the opening of a conference. So Rúhíyyih Khánum invited for lunch [both] Jane and me to have lunch with her. So that was the first time.
