Radiesthesia and radionics are very ancient practices, so it is normal that a semantic shift leads you back to esotericism, a very old practice of the power that every man seeks to exert over his fellow man.
The word esotericism refers to a doctrine according to which certain knowledge relating to "ancient philosophies" must only be transmitted to a small number of disciples and cannot be popularized. That which is esoteric should therefore remain in an airtight, closed, and occult domain, for the sole use of people wishing to exert power over human beings.

But in reality, the so-called gift of radiesthesia is a natural part of every human being that only asks to be exploited to become a very real and visible aspect in the light of day.
It is therefore natural that we turn away from esotericism regarding radiesthesia and radionics to bring out into the open, into the light, the fact that every human being is gifted and can therefore join the community of dowsers and radionic practitioners, for their own greatest good first, but also for the greatest good of all humanity.
We, dowsers and radionic practitioners, want to bring our practices out of the shadows so that they shine in a field accessible to all and become "exoteric" doctrines, that is to say, doctrines that can be taught openly in a form accessible to everyone.

As it would be stupid to forget the origins of our practices, Servranx editions offer a series of six books on esotericism taken in its ancient sense. These are esoteric subjects seen through the modern prism of radiesthesia and radionics. They show the path followed since the dawn of time by man, but above all, they demonstrate that there is no reason to remain in esotericism, especially when one can do much better and more intelligently by sharing our knowledge with all human beings.
