Something Gigi Young said in that video you linked to, @Nucifera, stuck with me. She was talking about the very slow evolution of humankind from a far more ethereal, even jelly-like form (with a bone structure closer to the fineness of fish bones, as opposed to that of mammals) to where we are now with our denser physicality. (This reminded me of 4th density vs. 3rd density.) She said that this density (or "denseness") of our bodies corresponds with our acute separation from the spirit realm, as well as our difficulty with remembering aspects such as past lives. Nevertheless, this physicality houses the spiritual, giving it strength (I believe she says or implies), or at least in this density.Gigi does claim that some material comes from trances, dreams, etc. Sometimes she cites those within a presentation, sometimes not. Some knowledge seems to be from studying esoteric literature. She seems fond of Steiner, but shows influences from Blavatsky, Gnosticism, Hindu classics, and others.
As to how new age sources are kept separate or blended in, I can't say. Much new age stuff seems to be adapted from older sources and concepts, but "new age" itself isn't something I study. I actually started watching Gigi partly to check the state of current new age thinking. It's also where I think Gigi can get into the weeds. E.g., in one talk she equated moving into the age of Aquarius as the end of the Kali Yuga, and that we're now in the Satya Yuga. I think she's off a bit on that, but what do I know. Gigi probably is far closer to the actual answer than classic sources that say (often indirectly) the Kali Yuga has ~431,995 years to go. Also to her credit, she got the sequence of the yugas correctly (AFAIK), which often seems not to be the case. [Hint: supposedly it's four ages, but in a sequence of seven for a full cycle.]
Why this interests me is because too often when people discuss spirituality there is a kind of hierarchy implied, as if the body were on a lower rung than the spiritual, when it could be said that the goal, to put it in psychological terms, is to no longer be dissociated (to whatever degree, depending on one's degree of trauma) but fully embodied, as in, fully spiritually embodied -- where the soul fully lands in the body, finally. And so the two -- body and spirit -- act as one. And so it's the degree that we are able to work through our trauma that corresponds to the degree in which we become spiritually embodied. And much of Young's talk indicates this, although she's not using the same vocabulary.
Note: I realize I'm conflating 'spirit' and 'soul' here, which are not necessarily interchangeable, but that's a somewhat different conversation -- something I would have to look into more and think about.
