Qui-gon’s explanation of the Force is one of duality; matter and energy, body and soul, mortal and God. A conduit, an intermediary, is required to bridge the gap and allow for a unification. It is a religious doctrine in keeping with the doctrinaire Jedi Order and its stratified system of authority and control.
Yoda dispenses with duality, implying that matter and energy are merely two appearances of the same essence. It is a spiritual teaching aiming at the highest truth, which is that all appearances of form and difference are merely shadows cast from the light of the eternal Force.
That’s a very interesting way to put it.
