I'd heard something about how some people, when getting up after the week of "sitting shiva" (mourning), take a walk around the outside of their house before going back to "normal" life. Has anyone heard of this practice? Does it have a source?
Although this is indeed the custom in many communities [some Chassidic communities circle the house seven times], there is no written source for it. Some explain that it is meant to escort the soul of the deceased to its proper place (Nitei Gavriel 136:16). Others maintain that the purpose of this custom is to demonstrate that the mourner is now permitted to rejoin society (Aveilus BaHalachah 29:1).
