Here the Zohar speaks about the dimension, or Sfirah, called Yesod. This is an immense reservoir that resides just above our physical dimension. All the Upper Worlds, or Sfirot, fill Yesod with their unique spiritual forces, where they are blended and prepared for transfer. Like a cosmic pipeline Yesod then funnels all this Light into our world, which is called Malchut. We can arouse a great amount of Light in the Upper Worlds through our actions, but unless the floodgates of Yesod are opened, the Light can never reach our realm.
The Aramaic passages that illustrate this procedure strengthen our personal connection to Yesod. They help us to open the pipeline from the Upper Worlds.
