"The goddess is red with the fire of life; the earth, the solar system, the galaxies of far-extending space all swell within her womb. For she is the world creatrix, ever mother, ever virgin. She encompasses the encompassing, nourishes the nourishing, and and is the life of everything that lives.
“She is also the death of everything that dies. The whole round of existence is accomplished within her sway, from birth, through adolescence, maturity, and senescence, to the grave. She is the womb and the tomb: the sow that eats her farrow. Thus she unites the ‘good’ and the ‘bad,’ exhibiting the two modes of the remembered mother. The devotee is expected to contemplate the two with equal equanimity.”
Joseph Campbell (discussing the image of the Goddess in Tantric mythology), The Hero with a Thousand Faces
