The Physical body is made up of the three fundamental elements: Water, Earth and Fire. Man has the most dense structure among the other types of creatures. It consists mostly of flesh, bones, blood. Inside the body coexist the three vital elements required by life: Spirit, Soul and Mind.
The immortal SPIRIT corresponds to the classical element Fire. It is like an ever-burning flame, which nobody can extinguish. It is the energy core around which the human being is formed.
The SOUL corresponds to the element Water. The Soul flows permanently through the blood vessels, supporting man’s life. The Soul resides in the middle of the heart and connects the Spirit (the eternal aspect) to the Physical body (the limited temporal aspect, which will die and decay one day).
In a wakeful state, the Spirit stays well hidden inside the brain, in a region called the "Great Vital", that looks like a gray matter sphere included in the cerebral trunk. The Spirit is embedded there in the eternal perispirit. The sphere which hosts It is made of perispirit matter. The perispirit consists of a semi-dense, etheric matter which permeates the gray matter of the brain.
The SOUL is an invisible etheric nucleus. Not even the greatest clairvoyants can succeed in seeing it. By the death, the Soul suffers a shock. It remains alive for a few more days, at the most 10 days, then it dissolves, its particles disperse into space.
The MIND is the work of the brain. A part of the brain creates and transforms thoughts, ideas, controls human feelings, coordinates the spiritual activity. The so-called "Mind" is, in fact, the result of cortex activity.
Each of these three fundamental elements – Spirit, Soul, Mind – because of their intense activity radiate energy beams which produce together the so-called "energy fields".
The SPIRIT emanates the most subtle, powerful and extended radiance. The spiritual field can scarcely be observed. Its colors differ at each individual, according to their Spirit’s degree of subtleness. The spiritual field is called the "causal field". Beyond it, there is only the Divine Absolute.
Next, less extended, closer to the human body, is the "mental field", which is the result of MIND activity. It is denser than the spiritual field, but not enough dense to be seen by anyone. Its colors depend on the individual persons, and their fineness corresponds to the quality of their Mind work. The more powerful and pure is the mental labour, the more lighter and brighter are the mental field colors. Dull dark and muddy hues belong to mental deficient people or to those who make many evil things.
The SOUL, by having an etheric structure, emanates a twofold etheric field. The first part has a reduced size, forming a double of the Physical body, which it pervades and covers like a shell. It is called the "etheric double", which is an exact copy of the Physical body, a little more bigger, and it has the task to keep the latter alive and control its entire activity. The etheric double is like a palace carrying all that is needed for the human being structure and functioning. If the man died, the palace unfolds and leaves - it is a flying palace. The bond between this palace and the body within is called the "etheric cord" which is bound to the brain at the back of the head.
The second part of the etheric body is called the "energy field". It contains both the etheric and physical bodies. The energy field itself is enclosed in the mental field, having a smaller size than the latter, but a greater density. So, in increasing order of density, next come the etheric double (denser than the energy field) and the physical body (super-dense). The colors of the energy field vary from individual to individual and from moment to moment. They are deeply related to the etheric double and physical body function.
