The Beloved Guardian explains that there is no requirement for one window to be oriented toward the East. In fact, he feels this should not be done; otherwise it will take on a practice of the Moslems with regard to their prayer niche, etc. I am sending a copy of this note to the German NSA, so they will understand.
The Guardian has also indicated that there is nothing in the teaching requiring one dome for the building, in fact, any dome. It is of course more beautiful, generally to have a dome, or even domes, but that is not a necessary requirement of the Temple.
Likewise the Guardian indicates, it is not essential that there be nine doors.
The real requisite is that the building should be circular in shape, having nine sides; that there should be nine gardens, walks, etc….
