Vladimir Megre's books about Anastasia are known as the "Ringing Cedars" series because of the sound that emanates from a Siberian Cedar when it approaches the end of its life cycle.
Siberian Cedar has a life span of approximately 550 years (a Fibonacci number). During the first 500 years of their lives these trees collect and store cosmic energy. "Day and night their millions of needles catch and store the whole spectrum of bright energy."
These trees share their energy with mankind, and if they get to a point where they have not shared enough energy, they start to "ring," communicating to man that it is time to "cut them down to make use of their stored-up energy on the Earth." This ringing lasts about three years, at which point they start to "lose their ability to give it back directly to man. Then they will start burning up the energy internally. This torturous process of burning and dying lasts twenty-seven years."
The benefits of Ringing Cedar to man are considerable. Anastasia's grandfather tells us that "even in one tiny piece of Cedar there is more energy beneficial to man than in all the man-made energy installations taken together. Anyone having one of these (Cedar) pendants would become kinder, more successful and more talented . . . and will be cured of many diseases."
