Hollow Earth/Inner Earth/Life and Civilizations Inside the Earth?

Is the earth hollow and is there life inside the earth?

In the "Magic Presence" Saint Germain states that there is indeed
intelligent life inside the earth, although it is not clear if it is meant
in the physical or astral or etheric plane.

This is just one reference amongst many alluding to the possibility
of life inside the earth. In one account a sailor accidentally sailed
through a pole opening into the inner earth and met human-like
life there. Supposedly there is an inner sun that assists life inside
the inner earth.

I was curious to know if you have any experience/information about
this issue? Thank you kindly.

as far as I can tell, the earth is not hollow.

There are, however, vast caverns inside the Earth's crust.

I have been to such places, in astral form, and they do exist.

Some do have artificial suns, like huge light bulbs.

I have been told, by the guardians of the ones I have been to, that these places serve the purpose of being safe places for portions of humanity to find shelter if the surface becomes inhospitable. And, that some of the other places in the crust are used by other races. Some of these races are from past civilizations, and some are from 'other' places, ET types.
