Is there a physical or higher dimensional city under Mount Shasta?

Question: Is there a physical or higher dimensional city in or under Mount Shasta in Northern California, USA? Is the figure Adama who is purported to be the high priest of this city real and is he who he is claimed to be? Are there habitable places underneath the earth for physical or other kinds of beings? Whatever else you care to share on this topic would be much appreciated.

Answer from the Ascended Master Mother Mary through Kim Michaels. This answer was given during the 2023 American webinar.

What we have taught is that there are four realms, four octaves, four aspects of the physical world. There is the purely physical material, there is the emotional, mental and identity realms. The surface of the earth is the place where physical beings live in the physical dimension. There are, despite the many claims out there, no physical habitable places under the surface of the earth. But there are, of course, beings in the emotional realm, the mental realm and the identity realm, some of which are under the surface of the earth in various locations. And some people, human beings, have tuned into this and thought that it was physical. There is a focus under Mount Shasta. It is not a physical focus. It is in the mental realm. It is not an ascended master retreat. It is not sponsored by the ascended masters.
