Desire is instinctive, arising from a place of seeking satisfaction (happiness, peace, fulfilment). It has always been true; since before that Desire inhabited human bodies, before we prowled into animal form, fluttered inside leaves at the treetops, grew in crystalline colonies.
Goddess did not make the body—directly. She is the original desire extending in all directions, eternally. This universe is an ordered fractal existence. Even in seeming chaos, that is true.
So, when "A Goddess Course In Miracles" talks about Goddess not creating something (bodies, sickness, war, etc.) and therefore it isn't real, it's difficult to hold the idea in contemplation. It's true and false at the same time. At the pure point of origin it's true.
And now at this point, since She is Creatrix of all, the truth is She did put this all into motion as the original impetus for now. But there's no point blaming Her for anything. Think of this like the breaking of ultimate generational trauma.
Since like attracts like, judging any actions—even Hers—as good or bad does not help those of us seeking peace to expand in new and satisfying ways. Experience is either satisfying or not. And we can only know through experience.
Something judged as good? Conditioning has trained us to want more of the same, which is at best pleasant stagnation. That which is bad we seek to avoid. But our desire to avoid is so active, that the bad fills our awareness until it's all we see. Also not a path to peace.
Ego and spirit are human constructs. (What, in fact, is not?) More bad and good judgements, transposed as the whim of your current truth dictates.
We can never return to Goddess because we never left Her. As fully divine human expressions, however, we can attune ourselves to the present moment where fresh experience of satisfaction is possible. And might possibly show us a way to peace.
