This room was a sacred space, a place that he had chosen to make especially his own, a place redeemed from mere "use" in which he would make a conscious attempt to be at rest and to put a part of his life in order. In short, this was the evidence that the man was able to pray.
From each heart is a window to other hearts
They are not separated like two bodies,
Just as, even though two lamps are not joined,
Their light is united in a single ray.
