Within the Pagan community, many worship the Goddess Isis of Ten Thousand Names. She is worshiped primarily as the Classical Goddess whose emphasis is placed on Her aspect as the Mother of Heru.
Throughout Egypt, there were statues of Goddesses seated on a throne, suckling one of the child-Gods (mostly Heru or Khonsu or the King). And these statues and wall reliefs portrayed many Goddesses doing this, not just Aset. Mut and Hetharu come to mind. This statue is called Isis Lactans by scholars. And this statue is believed to have inspired the statues of the Virgin Mary with Her son.
Heru-sa-Aset is the god of Kingship and community. He is the ruler and the child of His Mother. He and His Mother avenged the death of Wesir. He helps revive His Father and He stands in for the ailing person during spells where Aset is called upon to heal the patient. He is important to Her. He is Her son.
But She is much more than only His Mother.
Aset, the Kemetic Goddess, is the Mother or consort of Ra or Wepwawet. She is the trickster who beguiles. She is the Sorceress who rules and the magician who knows Her spells. She is the Goddess of knowledge, words of power and authority. She is the Goddess of sovereignty and the transformation of the soul. She is the Goddess of the dead and the crops. She is the fierce solar Goddess who shrieks as a kite, mourning Her husband. She is a shapeshifter and slays Apep every night.
And yes, She is the Mother of Heru, but that is not Her only trait.
