Sara Lyara Estes, known as "Lyara" on the Web, earned a B.S. in Zoology (cum laude) from the University of Michigan, a Lifetime Teaching Credential (K-9) from California State University, and an MBA in Information Systems from Golden Gate University. She also held real estate and securities broker’s licenses, had 1200 hours of training in energy systems and bodywork at the New Mexico Academy of Advanced Healing Arts, and received formal training in accessing other planes of reality from several teachers -- those in bodies upon the planet and those in nonterrestrial planes.

In her work in medical research laboratories, Sara developed the first reliable method for cloning tissue and identified a previously unknown cell type that proved significant in immunology related to organ transplants. She served as a key research subject in the original biofeedback experiments conducted by Dr. Joe Kamiya at Langley-Porter Neuropsychiatric Institute. She was also tested for her telepathic abilities and found to be 100% accurate in those tests. Walter Cronkite featured Sara in a 21st Century TV segment, "Miracle of the Mind." She also served as the Administrative Assistant for Computer Services at Cornell University's Graduate School of Business and Public Administration, as the Training Director for Data Processing for the State of New Mexico, taught sixth grade in Concord, California, and was the operations manager for Unisun, a solar energy company in Santa Fe, New Mexico.

On March 9, 1981, Christ appeared in her bedroom, put his hands on her head, and called her to the path that eventually led her to become the messenger for Operation Terra and the spokesperson for its mission. After being totally disabled by a collapse of her immune system in 1984, Sara turned to writing as one of the few things she could do while living life as a "bubble person," allergic to nearly everything. Her articles were published in several New Age magazines, and when she was well enough to work again, she began providing freelance book production services for authors and publishers, which then led to developing Web sites for them. Sara now lives in a remote area of the United States and devotes herself exclusively to Operation Terra at this time.
