Hakhel and the Materialization of Divine Unity

It could be said that it is in line with the unity of the Mitzvah of Hakhel as the verse states: הַקְׁהֵּל אֶת־הָעָם הָאֲנָשִים וְׁהַנָשִים וְׁהַטַף “Assemble the people: the men, the women, and the children,” and everyone together is uniting within the awe of Hashem.

And all of this is really drawn down below, into the actual materialism of this world, for this is how it will be when Moshiach comes (Neshomohs within physical bodies without any of the in between matters) where the Neshomoh, soul, will be sustained from the body.
