"XX. The Third Tunnel — A Secret World
The middle tunnel was the most important to both Lord Massini and the U.S. Government, which strongly requested to be kept secret to the public. This tunnel descended to extreme depths towards a veritable underground world, located near the center of our planet.
Those of you who are not familiar to the hollow earth theory, please note that there are important figures who support the theory that all planets are probably hollow on the inside, and bring interesting scientific arguments to support their claims.
Also, there are some very interesting and beautiful stories about people who allegedly traveled to this world. The realm is commonly known as Agartha, and the third tunnel was probably leading straight to it. It only makes sense that the shadow elite were not interested to make the discovery known to the people."

"The first public scientific evidence occurred in 1947 when Rear Admiral Richard E. Byrd of the United States Navy flew directly to the North Pole and instead of going over the pole, actually entered the Inner Earth. In his diary with other witnesses, he tells of entering the hollow interior of the Earth, and traveling 1700 miles over mountains, lakes, rivers, green vegetation and animal life. He tells of seeing monstrous animals resembling the mammoth of antiquity moving through the underbrush. He eventually found cities and a thriving civilization.
His plane was finally greeted by flying machines, the type he had never seen before."

"The Cintamani Stone, or Chintamani, long sought by treasure hunters, has captured the imagination of man through the ages as tales of this wish-fulfilling jewel have spread around the world"
"Apparently in possession of a piece of the Cintamani Stone, Roerich was said to have embarked on a quest to return it to Shambhala in the 1920s."

"Part of the stone was kept in a monastery in Tibet, the second in the Museum of Natural history in Manhattan, and the final piece in the city of Agartha"
"According to ancient texts the stone was sent from Tibet to King Solomon in Jerusalem, who split the stone and made a ring out of one piece"

"According to Roerich, the ring was set with a fragment of the Chintamani Stone."

"The main body of the stone is always kept in the Tower of Shambhala, although small pieces are sometimes transferred to other parts of the world during times of great change."

"this strange place at the center of the Earth has come to be known as Agharta or Agartha.
Modern myth describes it as a place of technological wonder (including, perhaps, flying saucers), where high priests, scientists and supermen hold incredible power, similar to the civilizations described by the likes of Raymond Bernard and Olaf Jansen."
"Shambhala is referred to as the capital city of Agharta, though this seems to be a purely Western construct. Entrances are said to exist at the Poles, or in caverns and tunnels honeycombed throughout the planet."
