Two letters from Rabbi Artson’s grandmothers, one written in 1972 and the second in 1983, highlight the ways that memory allows the past to live in the present. Rabbi Artson reflects on how people live in deeds, not in time, that our mammalian brains are literally shaped by our experiences so that our loved ones live in us. One of Judaism’s great gifts is crafting moments to visit our memories and gain strength from them.
