In counterpoint(for my tree hugging pagan friends) how is HaShem one/united with the Shechinah? this is where the real secret/sod of the mekubalim rings in. for the ways the Earth sphere moves/dances was always a closely guarded secret for the wisdomkeepers. Her rotation manifests as day and night(soul); Her revolution(about the sun) manifests as time/shanah-the seasons(light and dark) and Her precessional wobble manifests space/makom(heaven and Earth,tohu and bohu,morning and evening. these you will hear as the ten omakim/depths(sephirot) listed in the first words of Torah.
The sacred Makom/place we have now is related to what is known as the Eben Shetiyah, the foundation stone of the Beith HaMikdash HaShleishi- the" third holy House" or sanctuary. this is a time/place/soul where all the three "holy of holies"- kadosh kadoshim of time/shanah, place(space)/makom and soul/nephesh are unified in the physical world.
