Mariana's well-received book, Agartha - The Earth's Inner World, had just been released (2010) when she had a visitation from her cosmic friend and source of inspiration, Jan Fridegard, who told her he, too, had been to Agartha. He gave an account of his experiences there in the company of his dear friend and companion Lydia, whom we've met in a couple of previous books. They had also been on exciting adventures out in Space to the Pleiades, Sirius B, and Andromeda. Did Mariana wish to be his writing medium again? Of course In Agartha, they visit Porthologos, which houses a most extraordinary, gigantic library (with no books) that is several miles in length, wherein all human knowledge is contained. All one has to do is choose what one wishes to learn about, and in an instant, seemingly live holographic images appear, presenting the subject in question in a lifelike manner. In Agartha they meet the enigmatic Pilgrim, who imparts much of his immense wisdom to them and acts as their guide on several of their journeys. Among many other wonderfully fascinating places, they visit an intriguing research center, the Fortress, where notable inventions and discoveries evolve, and to which many eminent researchers from the surface world have been transferred, such as Darwin and Tesla. On the Pleiades (the Seven Sisters, comprised of many advanced Galactic Societies) no large cities exist, only very small communities in which virtually everyone knows one another and enjoys being in each other's company. Interesting accounts are given regarding the Pleiadean Parliament, their school system, and general way of living. Janne and Lydia also learn about its wildlife and sea people. Truly - this isn't a misprint - mermaids really do exist .... On Sirius B they make the acquaintance of a dolphin community, besides the amphibians - who have fish-suits. They further are privileged to experience a wondrously stupendous Evensong in the Ivory Cave. The journey ends in Andromeda, where all individuals are part of a higher consciousness, and life seems easy to live. They are shown healing houses, and even manage to visit a reptilian planet."
