A typical picture of Kali shows her squatting over her dead lovers body, his penis still in her, while she chews at his intestines. This mixture of creation or fertility and destruction illustrates the Goddess's dual aspect. In Greek myth, the Fates are the three goddesses who together rule over a persons birth, life, and death. One weaves a thread, which the other measures, and the third cuts. I've read that the principle numbers of the Goddess religions are odd numbers.
Goddesses tend to come in groups of odd numbers.
In Greek myths there are three Fates, three Furies, and Nine Muses. There is also, in Greek myths, and others, a Trinity of Goddesses - Maiden, Mother and Crone. The Maiden is the virgin hunter Artemis, or the independent women Athena. She is untied to any other God or Goddess, and her energy is her own. No one controls her.
