Well, she's definitely right that the divine masculine is talked about less by that name than the divine feminine. But that's because the divine masculine is usually what people are referring to when they say "God" in an Abrahamic sense. Or even just a creator capacity, perceiving the All as feminine is definitely the minority view. Some would say it's the esoteric view, it's definitely an esoteric view.
I disagree with her that the way of balance is for feminine people to get in touch with the divine masculine and vice versa. Why would a masculine person need to get in touch with a higher self that's feminine? What they'd need to do is be in touch with their masculine higher self and pair with someone who is in touch with their feminine higher self. That's balance, two spirits that are masculine and feminine on both a spiritual and physical level, operating in harmony.
This is something people miss in alchemy, they focus purely on the internal, forgetting that's a step. The hermaphroditic transmutation internally is an expression/reflection of an external process. Alchemy is about switching between these small-scale/internal views and the macroscopic views to maintain perspective while learning about the processes/patterns of nature/life. After you've done the internal work, you've got to return to the external. Balancing my internal femininity and masculinity ends at recognizing I incarnated as a man and connecting with a woman who recognizes she incarnated as a woman. We choose our incarnations for reasons.
I don't think a woman in touch with the divine feminine is Satan or channeling Satan, that's for sure. A woman in touch with the divine feminine is a woman at the height of her power in all the right ways.
The kali yuga is supposed to be a spiritual dark/iron age. I've read a lot of different theories and arguments on where we lie on the yuga timeline, but we're either a couple years past the deepest point of the kali yuga or a handful of years into the dvapara yuga or somewhere in between. In any case, it seems to me that both the divine feminine and divine masculine have been suppressed for all of living memory. The high priests and priestesses she describes were preserving a shadow of something greater, as were the Christian, jewish and Islamic religious leaders. By and large, there's only been honest attempts at preservations. There is only one God, so all who serve God serve the same God, I can't think of a way for there to be true discord among honest believers. (Before the divine feminine and divine masculine, there is the divine hermaphrodite that splits into the two, the divine masculine and divine feminine are unified while being separate. I'd say "before" being separate, but that kind of implies that the separation is something that ended the unity.)
I think what she's identifying as Satan/Lucifer isn't someone whose soul is in contact with the wrong aspect of the divine, but someone who is out of contact with the divine. Male or female, you aren't going to go wrong by getting in touch with a divine aspect. That wouldn't be a very divine aspect as I understand it.
