1. Introduction

According to all my many years of theoretical and practical research - the knowledge of ancient civilizations has greatly exceeded our current knowledge, both in the scientific and in the metaphysical domain, as evidenced by my numerous texts [e.g. 1, 2]. But - certain "God's Chosen Ones" inspired by the perfection of Creation still managed to occasionally, during evolution, convey to us part of the eternal truths and high knowledge from the "Cosmic Library”, the Morphogenetic Field or the Akashic Records…

One of them was Nikola Tesla, undoubtedly the greatest intuitive genius of this civilization, who was certainly one of the first scientists of this civilization who seriously approached the knowledge of ancient peoples.

The logical agreement, harmony and numerous analogies between the axiomatic principles of Sankhya with the experimentally verified parameters of modern physics, the expected values of the Quantized Energy Density Model [1] and - especially - Nikola Tesla's cosmology, are very reliable arguments that indicate the real possibility of realizing all Tesla's ideas - includingthe most controversial ones! For me, there is no doubt that they will be realized - but only when (and if) that civilization manages to achieve a sufficiently high level of awareness that will make such events realistic and possible.In any case, it is quite certain that Tesla's technologies will be the basis of all technologies of the 21st century, which, along with a better knowledge of natural energy phenomena, would contribute to a significant improvement in human health and the living conditions of mankind.

But - in order to understand Tesla's original statements based on etheric technologies, which - due to the arrogance and ignorance of official science - have been "pushed" into the domain of esotericism for a whole century, we must - in addition to the material, accept the very real existence of the spiritual aspect of our reality - and this is only possible by "uniting science and spirituality" and bringing their views of the SAME REALITY closer together from opposing aspects. The synthesis of scientific and spiritual knowledge embodied in the Model of Quantized Energy Densities, through observed analogies, symmetry and harmony between the material and spiritual aspects of reality offers us a really beautiful, very simple and logical structure of Absolute Reality, the possibility of a better understanding of individual entities and interacting mechanisms in the structure of the Absolute, which consists of an immense wealth of manifested and unmanifested, material-spiritual phenomena - that infinite ocean of various frequencies, vibrations, divine super-substance from which all things are made, from which allforms and lives.

The holographic structure of the fractal type of our Reality implies the existence of analogies so that Tesla's famous sentence: "Considering light as a sound wave...", with which he begins his calculation of ether parameters really makes sense but also has a realistic physical basis.…The established correlations and hierarchy of "sub-photonic phenomena" in this paper significantly clarify the "image" of Absolute Reality, but also indicate the EXTREMELY great importance of Nikola Tesla's legacy of his Ether Technologies.
