Rabbi Shai Tahan says that the one who runs the world is only the Holy One, blessed be He. He says that even if it seems that we are doing, after all everything happens from above.
The same is the case with the establishment of the Mishkan, he says. Rabbi Tahan: Everything we do in life, on a daily basis, is all in the 'as if', because we are not We do, but The Holy One. He enlivens the world every moment.
