"Pluto is named for a masculine Greek God a.k.a. Hades, whose name means "riches" according to A Guide To the Gods by Richard Carylon, "indicating the wealth of the earth in which Hades has his domain." His consort is Peresphone and he is feared as the god of death, but also seen as the "generous god of wealth." His domain is thought of as being under the earth, but in reality it may simply be anywhere we experience our inner depths, the void, the place of transformation. These are the mysteries of Pluto originally associated with the feminine mysteries of death, regeneration and rebirth presided over by Scorpio and the dark goddesses, Isis, Selkit, Erishikegal, Kali, Pele, Hecate, Cerridwen, and Peresphone to name just a few. The planet Pluto rules the sign of Scorpio and has a strong dark goddess, sorceress, enchantress energy." ~ excerpted from an article on the Shamanic Astrology site (love that site!)
In WWRWTW, several myths are offered as parallels for the La Loba myth, and one of them is the myth of Osiris and Isis. As I am going through a Pluto transit, I feel such a strong pull towards and connection with Isis. The story of Isis really symbolically encompasses the journey Pluto takes you on. So if you want to work with Pluto reading up on Isis is one way to go. I highly recommend Isis and Osiris: Exploring the Goddess Myth by Jonathon Cott. And check out a short article on the Aspects of Isis.
