There are many names for the Celestial Being, and it can harder to define than air. Worldwide there is Lady, Goddess, Deity, Loki, Yahweh, Father, Xochiquetzal..., well you get the idea. Many Pagans prefer to use a gender free word such as 'Spirit'. For me, I use 'Divine Friends'.
My book also gives a modern twist. A way to honor those Gods and Goddesses in the twenty-first century. For example, the first Goddess listed is Valkyries. An ancient ""warrior maiden on winged horses"". How does a twenty-first city boy with no spear or horse honor her? ""Honor their friendship by helping veterans of war or by feeding the homeless"". Something anyone today can do easily.
