The following is an excerpt from the book "Secret of the Andes" written by Brother Philip.
The Origin of the Brotherhood of the Seven Rays.
Lemuria is the name for the last part of the great pacific continent of Mu. The actual destruction of Mu and its submergence began before 30,000 BC This action continued for many thousands of years until the final portion of old Mu known as Lemuria was also submerged in a series of new disasters that were terminated between 10,000 and 12,000 BC This occurred just prior to the destruction of Poseidonis, the last remnant of the Atlantic continent, Atlantis. Lord Amaru-Muru(God Meru) was one of the great Lemurian sages and the Keeper of the Scrolls during the last days of doomed Mu.
It was well known to the masters of Lemuria that the final catastrophe would cause gigantic tidal waves to take the last of there land down into the angry sea and oblivion. Those working on the Left Hand Path continued diabolic experiments and heeded not 'the handwriting on the wall,'
The Masters and Saints working on the Right Hand Path began to collect the precious records and documents from the Libraries of Lemuria. Each Master was chosen by the Council of the Great White Hierarchy to go to a different section of the world, where, in safety, he could set up a School of the Ancient and Arcane Wisdom. This was to preserve the scientific and spiritual knowledge of the past. At first, for many thousands of years, these schools were to remain a mystery to the inhabitants of the world; their teachings and meetings were to be secret. Hence, they are called even today Mystery Schools or the Shan-Gri-Las of Earth.
Lord Meru, as one of the teachers of Lemuria, was delegated by the Hierarchy to take the Sacred Scrolls in his possession along with the enormous golden disk of the Sun to the mountainous area of a newly formed lake in what is now South America. Here he would guard and sustain the focus of the illumination flame. The Disk of the Sun was kept in the great Temple of Divine Light in Lemuria and was not merely an object of ritual and adoration, nor did it serve that single purpose later on when it was used by the High Priests of the Sun Among the Incas of Peru Amaru-Muru journeyed to the new land in one of the silver needle airships of the time.
While the final portions of the former continent were breaking up in the Pacific Ocean, terrible catastrophe was taking place all over the Earth. The Andean range of mountains was born at this time, and disfigured the west coast of South America. The ancient city of Tiahuanaco (Bolivia) was at that time a great seaport and a Lemurian empire colonial city of magnificence and importance to the motherland. During the ensuing cataclysms it was raised from the sea level and a mild, and a mild tropical climate to high on a barren, wind-swept plain and a frigid arctic-like climate. Before this took place, there had been no Lake Titicaca, which is now the highest navigable lake in the world, over twelve thousand feet above sea level.
So, it was to a newly-formed lake that Lord Meru arrived from sunken Lemuria. Here, now known as Lago Titicaca, the Monastery of the Brotherhood of the Seven Rays came into being, organized and perpetuated by Amaru-Muru. This Monastery, which was to be the home of the Brotherhood throughout all ages on Earth, was placed in a immense valley that had been created during the days of the birth of the Andes, and was a strange child of Nature in that its exact disposition and altitude gave it a warm, semi tropical climate where fruits and nuts could grow to phenomenal size. Here on top of ruins that had once been at sea level, like the city of Tiahuanaco, Lord Meru had the Monastery constructed of gigantic blocks of stone cut only by the energy of primary light force. This cyclopean structure is the same today as it was then, and continues to be a repository or Lemurian science, culture, and arcane knowledge.
The other Masters of Lemuria, the Lost Continent, journeyed to other parts of the world and also set up Mystery Schools, so that Mankind would have throughout all time on Earth the secret knowledge hidden away, not lost, but hidden, until the children of Earth had spiritually progressed to study again and to use the Divine Truths.
The secret science of Adoma, Atlantis, and other highly advanced world civilizations is to be found today in the libraries of these schools, for these civilizations also sent out wise men to found Inner Retreats and Sanctuaries throughout the world. Such Retreats were under the direct guidance and guardianship of the Great White Brotherhood, the Hierarchy of Earth's spiritual Mentors.
The valley of the Monastery of the Brotherhood of the Seven Rays is known as the valley of the Blue Moon and is located high in Andes Mountains on the northern, Peruvian side of Lake Titicaca. Lord Meru did not immediately set up the Monastery on his arrival at Lake Titicaca, but he wandered for many years, studying and fasting in the wilderness, where he was joined by others who had escaped the catastrophes. He was originally accompanied by his feminine aspect, Amara-Mara (Goddess Meru), when he departed from Lemuria in the needle-like airship. These were not space craft, but were used by the Motherland for trade between the colonies.
The Brother hood of the Seven Rays had known existence countless ages before the time during the time of the Elder Race upon the Earth about one billion years ago. However, it had never before had a monastery where students of life, highly advanced on the Great Path of Initiation, could come together in spiritual harmony to blend the flow of their life streams. Each student came into existence one of the Seven Great Rays of Life, as we all do, and these rays were to be blended by each student weaving his, or her, Ray, as if it were a colored thread, into the tapestry which symbolized the Spiritual Life of the Monastery. Therefore, it was called the Brotherhood of the Seven Rays, also known as the Brotherhood of Illumination.
