Planes of expression: calculation and meaning

The planes of expression sort your name into four registers, mental, physical, emotional, intuitive: your doors into the world.

Planes of expression: the 4 planes in brief

  • mental
    Think, name, understand

    The mental plane is the plane of thought: it gathers logic and language, and pushes you to understand before acting.

  • physical
    Act and make it real

    The physical plane is the plane of action: it gathers the letters of gesture and practical sense, and anchors you in the concrete.

  • emotional
    Feel and connect

    The emotional plane is the plane of feeling: it gathers the letters of affection, imagination, and sensitivity to atmosphere.

  • intuitive
    Sense, seek meaning

    The intuitive plane is the plane of hunches: it gathers the letters of the search for meaning and of subtle signals.

What are the planes of expression?

Faced with the same situation, a move for example, four people do not start from the same end. The first compares neighborhoods and makes a list. The second is already renting the van. The third wonders which home will feel right. The fourth knows, without being able to explain it, that this is not the right time. The planes of expression describe these four doors.

The mental plane, sometimes called the cerebral plane, covers logic, language, and analysis. The physical plane gathers action, gesture, and practical sense. The emotional plane brings together affection, imagination, and sensitivity to atmosphere. The intuitive plane, finally, touches on hunches and the search for meaning. Each letter of the alphabet belongs to one of these four registers.

The planes belong with the personality traits, alongside the Expression number, with which they share a source: all the letters of the name. They do not measure intelligence or talent, but a preference, the most natural way to approach a problem. The plane with the most letters is called dominant; a plane with none is called absent. An absent plane does not mean an inability: it points to a register that needs more attention, and that people often learn to cultivate over the years.

The planes work at any age and in every area, from work to relationships. They shed light above all on misunderstandings: two people close to each other who do not come in through the same door may think they do not understand each other, when they are simply speaking two different languages.

How to calculate them

Write the birth first name and last name in capitals, without accents; then place each letter in its plane. Mental plane: A, G, H, J, L, N, P. Physical plane: D, E, M, W. Emotional plane: B, I, O, R, S, T, X, Z. Intuitive plane: C, F, K, Q, U, V, Y. Count the letters in each plane. The fullest plane is dominant; if there is a tie for first, all the tied planes are dominant. A plane with no letters is absent. Other schools sort some letters differently or add a second classification of letters; their results may therefore differ.

Common mistakes with the planes of expression

  1. Sorting the first name alone. The surname received at birth counts too, letter after letter.

  2. Naming a single dominant plane in case of a tie: Lucas Vincent places four letters in mental and four in intuitive, so two dominant planes.

  3. Taking an absent plane for an inability. It signals a less spontaneous register, one that can be cultivated.

  4. Sorting a letter by its pronunciation or its status as a vowel. The table is fixed: A is mental, I is emotional, Y is intuitive.

Frequently asked questions: planes of expression

How do you calculate your planes of expression?

Take each letter of your first name and surname and assign it to one of the four planes according to the distribution chart: A, for example, goes to the mental plane, E to the physical plane, O to the emotional plane, and U to the intuitive plane. Count the letters in each plane: the fullest one dominates, and a plane with no letters is absent.

What does an absent plane of expression mean?

An absent plane points to a register you do not use spontaneously: reflection, action, emotion, or intuition, depending on the plane. It is neither a lack of ability nor a flaw. It simply asks for more attention, and many people develop it over time, through experience or simple habits. The intuitive plane is the one most often absent, because its letters are rare in French.

Can you have two dominant planes?

Yes. When two planes have exactly the same number of letters, at the top of the distribution, both are dominant. You then move easily between two registers, for example from analysis to action. This double entry point is a flexibility; it can also create hesitation, when the head and the heart, or the gesture and the hunch, pull in two different directions.

Do the planes of expression go by other names?

Yes. The mental plane is often called the cerebral plane, and English-language authors speak of “planes of expression.” Some schools also link each plane to an element: air for the mental, earth for the physical, water for the emotional, and fire for the intuitive. For these authors, the letters are distributed as they are here; only the vocabulary changes.

Do the planes of expression change over a lifetime?

The distribution does not: it comes from the letters of the birth name. What varies is the use you make of each register. A dominant plane remains the natural entry point, but an absent plane can be worked on: with an empty physical plane, you may discover late in life the pleasure of tinkering, gardening, or walking for hours. The distribution gives a starting point, not a ceiling.

What is the difference between the planes of expression and the Expression number?

They start from the same letters, but do not treat them the same way. The Expression number adds up their values to get a digit that sums up the visible personality. The planes ignore those values: they sort each letter into a register and count how many each one receives. The first tells the image you give; the second, the door through which you approach a situation.

Should you include all your first names in the planes of expression?

In the main reading, the distribution covers only the original surname and the first given name. The full reading adds the middle names, which can shift the balance: a middle name rich in I, O, or R strengthens the emotional plane, while a name like Yves raises the intuitive. The name you go by stays outside the calculation; you can distribute it separately, out of curiosity.

Can you have three or more dominant planes?

Yes, the method treats as dominant every plane tied for the lead, with no limit on the number. The situation arises more easily with few letters: Vincent, taken alone, puts two letters in the mental plane, two in the emotional, and two in the intuitive. Several dominant planes describe a way of switching registers depending on the situation, sometimes with difficulty knowing where to start.

How do the planes of expression appear in the report?

In the “Who you are” chapter, the report first gives your four counts: mental, physical, emotional, and intuitive. A text follows for each dominant plane, then a text for each absent plane. These pages complete the numbers with a reading about method: not what you are, but how you tackle a problem, a decision, or a project.

  • Dominant number

    The dominant number is the value that comes up most often in the letters of your name: a resource you draw on without thinking about it.

  • Excess number

    An excess number is a digit that accounts for more than a quarter of the letters in your name: a quality so abundant that it overflows.

  • Missing number

    A missing number is a digit from 1 to 9 absent from your name: a quality to learn, never a flaw.

  • Who you areActive number

    The active number, also called the first name number, describes the person your family, friends, and neighbors know, away from any official role.

  • Who you areHereditary number

    The hereditary number describes what you take from your lineage: values, reflexes, and supports drawn from your birth surname.

  • Who you areInitials

    Your initials are the two letters that open your identity: the impression you leave before anyone really knows you.

  • Who you areInitials number

    The initials number captures the impression you leave at first contact, based on the first letters of your first and last names.

  • Who you areFirst vowel

    The first vowel shows your most immediate reaction when an event upsets your plans, before reflection kicks in.
