When the Holy One Blessed be He Created man in the world, he formed him in the share of the upper world. He gave him a strong force in the middle of his body, at the place of the heart that gives strength and nourishment to the entire body. The heart is connected and connect to the upper levels through the brain.
The world was Created in a similar way as one whole around a center that is the Holy Land of Israel and the aspect of the heart that provides strength and nourishment for the entire world.
When God said (Genesis 1:26) “And God said: ‘Let us make man in our image” it didn’t mean that God’s image is similar to humans. The Meaning is that man was created in the same spiritual form/image as God. The ‘image’ is the Tree of Life and the center/heart is the center column, Zeir Anpin that provides for all of us in Malchut the strength and nourishment we need.
