Matter is not more real than the spirit.
I am among those who believe that humans are basically superior to angels.
And our superiority lies in the fact that we have a dual existence.
We are amphibian creatures.
We move between matter and spirit while most of the creatures of the world are either/or.
We live in two worlds, and it is just this double ability of ours that gives us superiority over angels.
We have a dual attachment, so when we lose one of them, we lost our superiority.
–Rabbi Adin Steinsaltz
