"Thus this room (in which I find myself) which has neither doors nor definite limits, is today the highest of the dwellings of Paradise, for the Tree of Truth lives herein. It would seem that all the atoms of the room, all sing in one voice, `In truth, I am God! There is no other God beside Me, the Lord of all things.' And they sing above all the rooms of the earth, even above those adorned with mirrors of gold. If, however, the Tree of Truth abides in one of these ornamented rooms, then the atoms of their mirrors sing that song as did and do the atoms of the mirrors of the Palace Sadri, for in the days of Sad ( Isfahan) he abided therein." ("Le Bayan Persan," vol. 1, p. 128.)
