Known as middle Earth it represents the personality, ones Ego, our conciousness, or lower self. MidgarthR is part of the stability of order within the Nine Worlds that includes AsgarthR , and LjossalfheimR . This is the realm of shape and formation of all humanity. All things in MidgarthR take shape or form in SvartalfheimR. Everything formed here manifests in MidgarthR . HelheimR is the realm of the dead, the Underworld.
All souls undergo rebirth here.
Our ancestors are ever present and actually nourish the living with their presence. This is an important part of Ancestor Worship. If this is true, honoring our Ancestors will insure their rebirth to another level or reincarnation which is part of my tradition. It is very difficult to leave HelheimR which is in the realm of the Goddess Hel , daughter of Loki. It takes a great deal of power provided from the outside.
