Hod sits below Gevurah and across from Netzach in the Tree of Life.
All the sephirot are likened to different parts of the body, and Netzach and Hod are likened to the two feet of a person: right foot and left foot. Feet are usually only the means of a person's activity. While the hands are the instruments of action, the feet bring a person to the place where he wishes to execute that action.
In a mystical sense, in which the Tree of Life is supposed to be a roadmap to "consciousness," Hod is where form is given by language in its sidest sense, being the key to the mystery of form. (Perhaps this may be an adopting of the point of view of the psychoanalyst Jacques Lacan), our unconscious desires come from Netzach, and are given form in the symbolic realm by Hod, manifesting unconsciously through Yesod to Malkuth."
