Once I requested to be in Baha'u'llah's room when He was revealing Tablets. This request met with His approval. As I entered His room, I heard streams of words sweeping along in a torrential flow from His lips. It seemed that the atmosphere, the floor, the walls, and every atom in the room was filled with perfume. Only those who have had this indescribable experience can ever imagine what I mean. The flow of revelation continued for about five minutes. Then Baha'u'llah said to me, "You have on several occasions been here when the revelation of Tablets has taken place. Should the people of the whole world wish to be present and hear the words of revelation, We would permit them. But since We have approved courtesy and ordained it upon men, we are reluctant to display this power publicly."
