‘Divine Femenine’ is phrase most people use to refer to Goddesses of different cultures and other spiritual entities that are understood as being ‘feminine’. But what ‘feminine’ means in terms of divinity?
As divinity are not men or women, feminine divine do not necessarily refer to a gender differentiation based in a body or physical difference. Most goddesses and gods are represented as anthropomorphic and zoomorphic figures, like in Greek mythology or in the Egyptian pantheon, which give the possibility of identify them with a gender and sexuality. But this is just an iconographic representation not the divinity in itself. I do not think any religion worship really images or statues as divine. I think those are just tools to get the mind closer to the idea of the energy, although this image can be charge with blessings and intentions, used for magic spells and be worship in a dramatic scene, this does not mean that the image itself is the divine. Many spiritual traditions avoid physical representation but still have feminine descriptions of divinity in texts and poetry, that is the case of the Shekinah in Kabbalah, often described as a bride, a mother or daughter. The Christian god is supposed to lack of images, but is often described as a father or son too. Many people can argue that this is just the use of the language, and that this does not suppose a gender. This is the same I mean about pictures, so it is not a reason to avoid the distinction.
But the fact is that there is some divinities that are considered feminine, and the consequence is that they attributes are also considered feminine and finally related to woman roles. If this is a matter of language or not, it should be discuss. These feminine qualities will be very different depending on the culture, so we can find the feminine related to some planets, plants, animals, letters, skills, etc.
Some people may believe the creator is of feminine nature, being able to bring live alone: goddess unborn and pregnant of the world, as in parthenogenesis. Others may believe the divine feminine is coupled with the divine masculine in order to create, as if it were a human couple. Other may believe the divine feminine is part of a hermaphrodite or an androgynous entitie that also can create alone by auto-fertilization. Some people believe the divine do not have gender in the end.
In modern times we talk about a divine feminine to state a difference with the divine masculine, as this one seemed to be more present in western religions lately. Some people prefer to talk about the Goddess, and personally I prefer to use the name of a divinity rather than a general category.
