The Lulav meditation
The Holy Ari explains that when God created the world he distanced the Light from a ‘Middle point’ to create the world of Malchut. Then, a line of Light was drawn down from the outer /endless into the middle, which formed the Sefirot from above to bellow.
The mitzvah of the Lulav on Sukkot puts us back in the middle point. The Lulav represents the original line of Light and the six directions connect us to the sphere of Light that surrounds us. We can now connect to the flow of the Light of Chessed that comes down to the world after Yom Kippur. The Lulav and the Sukkah are our special tools to draw this Light into our lives.
