One of my teachers, Chana Bracha Siegelbaum, posts this week about the mikdash (sanctuary) in our hearts, a fitting study for the Torah portion this week, Terumah.
Her post is called
"Making a Sanctuary in our Heart
We know that all the mitzvot of the Torah are eternal, but how is it possible to fulfill the mitzvah of building the mikdash today? A person is like a mini-cosmos. Therefore, the command “make me a sanctuary” implies that we all are charged to perpetually make a sanctuary in our heart, in order to prepare a place for the Divine presence to dwell. When G*d dwells in the heart and soul of every one of us, the continuation of the verse: “that I may dwell among them” is fulfilled."
Although I try to remember everyday, the day I remember my responsibility to be a sanctuary is usually Shabbos. On weekdays I know that there is a flame burning in my heart, but on Shabbos it becomes my primary activity to remember and uphold the sacred space I occupy.
