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.
Solitude is an attitude, an attitude of gratitude. It is a state of mind, a state of heart, a whole universe unto itself.
