I just watched a beautiful video produced by the Jewish Learning Institute how when G-d first decided to dwell below – as the verse states “The highest heavens don’t hold you, but This House Shall” – in the Beis Hamikdosh (the primary Synagogue and place of worship of the Jewish people for over 1,000 years (including the Mishkan.)
The Holy Baal Shem Tov tells us a meaningful instruction, that the fact that G-d could dwell within a 10 X 10 room – the holiest location in the world, called the Holy of Holies, where the Cohen Gadol would enter only once a year on Yom Kippur to offer prayer – a position coveted so much that the Divine experience was one in which the spiritual holiness of the individual, to be able to receive it, had to be absolute – yet if G-d could descend into a physical space, how much infinitely more so can He descend into you – a spiritual space.
As such two lessons specific for our time are most important: a. a Jew is never abandon – the law of space is that if one thing fills a space, though it may be invisible, it is everywhere – in point of fact, our possiblity of not feeling G-d is only our perception (darkness) however just as the original light of Creation (interestingly, the original light of the big bang is right here and measurable, just on a different wavelength) is always present, hence though we may be “blind,” the fact that G-d is with you never changes! b. as Reb Menachem Mendel of Kotzk said: though G-d is everywhere He is seen, wherever and whenever you let Him In!
Every Mitzvah we do, Opens, Reveals, Invites, Unifies, G-d Within Man.
