7.4-5 Bhumih  etc.  Apard  etc.  [The demonstrative]  'this' denotes  what is being perceived  [as objects] through  sense-organs by all men at the stage of mundane life.  This is only one and at the same time is divided eigth-fold.   Therefore the universe is one and unitary, because it is made of one single material cause.  By  this statement, monism is demonstrated even while following  the Prakrti theory.  The selfsame  Prakrti has become the living one i.e., the personal Soul.  Hence it is superior  [to what has  become eight-fold].  It also belongs to Me alone and  not to anybody else.  This  Prakrti is  [thus]  two-fold and varied in the form of the universe consisting of the  knowables and the knower.  That is  why this  Prakrti  (the basic  material  nature),  being the substratum of all beings reflected on the surface of the clean mirror, viz., the Self , is nothing but Self's own nature and [hence]  never leaves Him.  This world :  the Earth etc.  [mentioned in the  4th verse].
