Corbin is very insightful.
When he spoke of "their" aspect, that is the thing you look to. What are the stories and myths? How can those apply to your every day life?
I work with the Celtic pantheon in particular, mainly because that is the focus of my group and part of my heritage, But the lessons and strengths can be observed from many different regions who's Gods and Goddesses may have similar "aspects" for living a good life. For instance Loki can be examined when chaos is around. Persephone may reveal the need for time out, rest or working on a shadow and Nuit may be called upon when protection is needed.
The deities didn't just appear out of thin air, they may or may not have been real people at one time who's contributions to life were so significant that their lore was handed down throughout time. That gives strength to their aspect. Others who may not have been real, were still real stories of caution, truth. and the cycle of time etc...
The egregore to each individual deity has been formed already, we can tap into this power source because there are many folks who keep them alive.
Perhaps in a thousand years from now Batman will be considered a God because of his stories and quest for justice...because
so many people have given him power already. His egregore is strong.
I believe we have a thread on our superheros....
