Glossary

The language of The Master Key System, defined. Use this as a companion to the weekly readings — return to it whenever a term feels half-understood.

The Master Key System

The 24-week correspondence course written by Charles F. Haanel and first published in 1916. Each week is one part — a lesson, a sitting exercise, and a set of questions — designed to be lived for seven days before moving on.

The Universal MindWeek 1

Haanel's term for the one creative intelligence that pervades all things. The individual mind is the means by which the Universal becomes personal and acts in the world.

The Objective MindWeek 2

The conscious, reasoning, decision-making aspect of mind. It directs attention, chooses, and accepts or rejects what enters the subconscious.

The Subjective MindWeek 2

The deeper, receptive, creative aspect of mind. It accepts what the objective mind impresses on it and is the seat of memory, intuition, and the connection to the Universal Mind.

The Solar PlexusWeek 3

Haanel's metaphor for the brain of the subjective mind — the sun of the body. Through relaxation and attention to it, vital energy is generated and radiated. Located behind the stomach.

Sitting (the Exercise)Week 1

The disciplined daily practice at the heart of the course: sit in the same chair, in the same posture, relaxed and motionless, holding the week's specific instruction. Begins at fifteen minutes and never grows shorter.

ConcentrationWeek 4

Sustained attention on one object, idea, or quality without wandering. The work of every week is to grow the capacity for this — first physically (stillness), then mentally (a single thought), then qualitatively (a single feeling).

VisualizationWeek 7

The act of forming a clear, definite mental picture of what is desired, held with feeling, until the subconscious accepts it and the means of its expression begin to appear.

Causation (Law of)Week 4

The principle that every effect has a cause, and that thought — held with feeling and conviction — is itself a cause in the world of effects. To change conditions, change the thought that produced them.

The Law of AttractionWeek 7

Haanel's formulation: like attracts like. The dominant mental attitude assembles around itself the people, circumstances, and resources that match it. Not magic — the way attention organizes action and perception.

Omnipotence, Omniscience, OmnipresenceWeek 5

The three attributes of the Universal Mind: all-power, all-knowledge, all-presence. The individual draws on these to the degree that the channel — the personal mind — is clear and aligned.

Inductive ReasoningWeek 9

Reasoning from particulars to general law — from observation to principle. Haanel uses this to argue that the operation of mind, observable in the small, must hold in the large.

The SilenceWeek 6

The condition entered during the sitting when thought stills and the subjective mind becomes receptive. Not absence but presence — the ground from which insight arises.

AffirmationWeek 8

A definite, present-tense statement of truth held with attention until the subconscious accepts it as fact. Used in The Master Key as a tool of concentration, not as a slogan.

FaithWeek 11

In Haanel's sense, the calm expectation that the law of cause and effect will operate. Not belief in spite of evidence — confidence in the process before its visible result.

InsightWeek 12

The faculty by which one sees into a situation, problem, or person and understands directly. Cultivated by the silence and by the sustained focus of the daily sitting.

The Law of GrowthWeek 13

What you give attention to grows. Attention is the gardener; the subconscious is the soil; the thought-image is the seed.

VibrationWeek 14

Haanel's term for the quality or frequency of a thought-feeling. Conditions in the outer world mirror the dominant vibration of the inner. To change the outer, raise the inner.

HarmonyWeek 17

The natural state of the mind aligned with the Universal — the absence of inner contradiction. The mark of mastery is not effort but harmony.

The Subconscious Imprint

A pattern accepted by the subjective mind and acted upon automatically. The course is a 24-week practice of choosing what gets imprinted and what does not.

Mental EquivalentWeek 19

The clear, complete inner image of what is desired. Until the mental equivalent exists, the outer cannot. The work of the sitting is to build it.

ServiceWeek 23

The mature expression of the Master Key principles. Power is given for use, and use is what one does for the larger life. The final weeks turn personal mastery outward.
