The existing names of the energy bodies in any of the familiar traditions is nothing more than an agreed convention.
Therefore, for the convenience and ease of understanding particularly of a reader unfamiliar with "esoteric" doctrines, we shall call the first energy body "ethereal", the second "astral", the third "mental", and so on.
The human energy system consists of several energy bodies (levels), that differ in shape, energy density, and vibratory rhythm (frequency).
Most importantly, though, they have different characteristics. In examining the effect of the Wands of Horus on the human organism, we shall stick to the first two energy bodies that are responsible directly for a person's bio-energetic rhythm and emotional state.
The first (ethereal) energy body consists of vibrations and temperature rhythms in the person's physical capsule.
Therefore any process taking place in the physical body is immediately reflected in the first energy body.
For example, an inflammatory process has begun localised in the small of the back (lumbago).
That is followed by oedema and an increase in temperature that immediately finds reflection in the altered shape and vibratory frequency of the corresponding part of the first energy body.
Hence, influencing that part of the energy body and correcting the vibratory frequency leads to a reduction in the pain syndrome.
