There are different wavelengths, octaves, notes, harmonies, tones, vibrations, manifestations of the All That Is... There are many versions, renditions, takes, some misshapen and some perfectly whole and some in a process of the two. This is where the Polarity Plane comes into play.... There are varying vibrational frequencies and expressions of these frequencies; and yet all from the same substance and of the same substance.
Everything and everyone has two poles and in reconciling these expressions of the poles we connect in the center of Oneness. In the Eastern tradition of Hinduism this is called Samathi. The ultimate Samathi is Samadhi -- when death occurs; the denser physical body separates, there is an ultimate centering or connecting in this Oneness. Remember there are layers and levels to every manifestation of form. There are varying degrees within and that comprise the polarities and how they interact; as well as express.
