In this exhilarating description of mysteries inside the Earth, Radu Cinamar presents a unique way to penetrate the Inner Earth through the process of feeling and the effects that will develop from such an experience. To enhance the readers understanding of this very guarded subject, this book includes multiple illustrations that include depictions of Inner Earth geography. Familiar characters from the Transylvania Series also reappear, including the enigmatic Tibetan lama, Repa Sundhi, also known as Dr Xien, who states: If someone had a device or machine that could start up and go everywhere they want, especially towards the centre of the Earth, the machine would be blocked and stop at a certain point because of the frequency of vibration to be found there. Just how far you can go with such a machine can be limited by reason of your own con- sciousness which can in and of itself restrict the dimensional range of such a device or the extent to which it can penetrate other realms. This applies to both human beings as well as material objects. Your ability to access such a region is determined by what your own individual frequency of con- sciousness can or will allow you to experience. This is not only the story of an exciting adventure, it is an opportunity for initiation as you explore the frequencies of your own inner nature.
