In Bruce Moen's book I just read sth. about the Inner Crystal Core of the earth that defines "spirit gravity". The closer you are attached to the Core the denser&low-vibrational you are and the more bound you are to Earth material life. It also resembles Monroe's theory about gaining "escape momentum & velocity" for spirits relating to the Earth Life karmic incarnation cycle.

Have you been "in" the Earth one time? What are your findings?

Holy Wiki representig the "officially scientific" world view tells us it is mostly of iron.

In the 90ies a theory about a Crystal Core actually came up.

Moen also relates it to astrological principles, stating that each planet would have a crystal core with energy fields, creating a big clockwork of the solar system / universe.

Also there is said to be some remnant crystal structures up nearer to the earth's upper crust and influencing Earth Life and creating "energy points" (I felt reminded of the Seth book where Seth/Jane Roberts also talks about these points in different parts of the world). The Bermuda Triangle is said to be such a point since there it aligns with the field of Uranus.

Well ... of course, that is all weird and crazy stuff ...
