Their world, the Inner Earth, doesn't know night. A smoky sun, which is the nucleus of our Earth, hovers in the center. It hangs over 1,000 miles above the inner surface and provides for a pleasant orange hue and a constant temperature of about 24 degrees Celsius (75 degrees Fahrenheit). There's less gravity there than here, so you feel lighter.

Western scientists have tried to determine from the outer surface which elements this core consists of. This was done via a so-called spectrometer, an instrument through which the composition of materials can be measured by listening to the outgoing frequencies.

It turned out to be a spherical crystal of iron and xenon of millions of degrees hot and with an enormous density (8). The assumed diameter is approximately 1,300 miles. This core rotates much faster than the crust and, moreover, the other way. This acts as a generator, and this creates the magnetosphere around the Earth.
A quarter of Agartha consists of water, the rest is land upon which are built about one hundred crystal-like cities. The capitol city where their government resides is called "Shamballa the Lesser", other cities have names such as Posid, Shonshe, Rama and Shingwa.

The crust of our planet is like a Swiss cheese. Over time caverns and grottos have formed that are hundreds of miles long. The satellite cities in the Agartha network are found in some of these spaces (10). Some lay very near under the Earth surface, like the big city of Telos (11) under Mount Shasta in California. Telos reaches up to about half way in the mountain and thus lays partly within the surface of the Earth.

Not everywhere do we find magma, and it doesn't go any deeper than 20 miles. The rest of the crust is used by the Agarthans for making connections between satellite cities and the continents within the Earth. Most cities have self sustaining eco-systems.
Organization

The "Counsel of Twelve" which governs Agartha is a group of six men and six women. It is a compassionate board of directors that provides guidance and protection to the entire citizenry. The High Priest performs other important functions for the people.

All cities and houses are connected by a most ingenious, spiritual computer system. It functions with the use of amino acids and is used for internal and galactic communication. It also keeps check on the health of the citizenry and monitors their intake levels of vitamins and minerals.

There is no use of money in Agartha. People use the barter system and there is plenty of everything for everyone. Energy is free. The cities are accommodated with moving sidewalks and for shorter distances a sort of scooter is used. An electromagnetic system called "the tube" is used for travel from one city to another. It can reach speeds up to four thousand miles per hour.

The Agarthans are fully integrated into the galactic way of interaction and are part of the Confederation of Planets. They make space-flights in ships that are capable of changing dimensions which makes it impossible for us to see them. It is at crowded places such as Mount Shasta and Mount Adams where space-ships come and go all the time. Contactee James Gilliland, built his ranch at the foot of Mount Adams, to search the night skies with visitors from all over the world. With binoculars they watch the light-ships move in and out of the mountain. The outside of the mountain is no obstacle for their ships since they dematerialize without any problems.
Of course the illuminati, who make our lives on the surface of Earth so challenging, have also tried to conquer the Inner Earth. Due to the Agarthans' superior technology and the protection of the Confederation, the Agarthans had no difficulty stopping those attempts.
