ועשו לי מקדש ושכנתי בתוכם )כ"ה ח’(
פרש"י ועשו לשמי בית קדושה
A Yid must see to it, to bring Kedusha (Holiness) in his private “House”. His home and family life should be with Kedusha. And that is called a Mikdosh (sanctuary).
Rav Menachem of Amshinov ZY”A – Der Torah Kvall
ועשו לי מקדש
Mikdosh is a language of preparation – invitation. When a Yid designates a “Mokom Tohor” - a pure place in himself for השראת השכינה (Devine resting), then Hashem says ושכנתי בתוכם I will dwell in their midst.
Sefer Divrei Shmuel – Slonim
The Kotzker ZY”A said on the verse איה מקום כבודו the Malochim ask where is the place of Hashem כביכול. To which is the answer, “וואו מען לאזט אים נאר אריין" - “Where he is let in”. If one acts with קדושה Holiness, he merits השראת השכינה.
