John Demartini

John Demartini is one of the featured co-authors of The Secret and one of its principal interpreters of the relationship between thought, intention, the body, and personal transformation. The book presents him not only as a philosopher and healer but also as a chiropractor, author, international speaker, and specialist in personal transformation. His decisive contribution is to translate the law of attraction from an abstract proposition into a program for reading everyday circumstances, physical symptoms, and emotional states as consequences and feedback from the mind.

Identity and Background

John Demartini is introduced as a philosopher, chiropractor, healer, and personal transformation specialist. The book’s biographical material adds that he was once told he was learning disabled, yet later became a doctor, philosopher, author, and international speaker. For many years he operated a successful chiropractic clinic and was named Chiropractor of the Year. His later work made him a consultant to health professionals, and his methodologies for personal transformation were said to have helped thousands of people find greater order and happiness in their lives.

This trajectory establishes the pattern through which The Secret invites readers to understand him: an earlier limiting description does not define the person’s permanent identity. His biography therefore functions alongside his teaching. The contrast between being labeled learning disabled and becoming a doctor, speaker, and authority on healing embodies the book’s larger insistence that present circumstances are residual effects rather than final definitions.

Thought, Intention, and Reality

Demartini explains that people attract the predominant thoughts held in awareness, whether those thoughts are conscious or unconscious. In his account, the important change is not merely learning a new slogan but becoming aware of the thoughts that have previously operated without examination. Knowledge of The Secret awakens people to the law and to the power they exercise through their thoughts.

He also argues that the law of attraction can be observed throughout ordinary life. The people, employment, circumstances, health, wealth, debt, joy, car, and community surrounding a person are presented as things drawn to that person like a magnet. The formulation makes thought the primary organizing force of experience: what a person thinks about is what that person brings about, and a whole life becomes a manifestation of the thoughts moving through the mind.

This principle is extended to circumstances that people ordinarily experience as external or accidental. The book states that everything surrounding a person, including the things that person complains about, has been attracted. It acknowledges that readers may reject this claim when considering a car accident, a difficult client, or debt, but treats accepting the claim as transformative because it replaces helplessness with a sense of agency.

The same reasoning is applied to collective catastrophe. Demartini’s account says that people caught in mass historical tragedies need not have imagined the exact event; their persistent fear, separation, or powerlessness is said to have matched its frequency. This is one of the most morally demanding applications of his framework, because it shifts explanation away from luck or wholly external circumstance and toward the frequency of thought. The book then presents the reader with a choice between believing that bad events can strike without control and believing that life experience is in the reader’s hands.

The Body, Healing, and Disease

Demartini’s account of health begins with the claim that the body is produced by thought. The book describes medical science as increasingly aware that thoughts and emotions can determine the physical substance, structure, and function of the body. In this model, the body is not treated as separate from consciousness; it becomes the material register through which mental and emotional patterns appear.

He invokes the placebo effect as evidence of the mind’s influence in healing. A placebo may be presented as an inactive sugar pill, yet when a patient is told that it is effective, it can sometimes produce the same effect as, or an effect greater than, the medication designed for that purpose. Demartini’s use of this example supports his broader contention that the human mind can be the largest factor in healing, at times more influential than medication.

The book nevertheless includes an important qualification. When illness is acute and could lead to death, medicine is described as the wise choice while the person also explores what may be occurring in the mind. Demartini does not present mental healing as a reason to reject medical treatment; instead, he says that every form of healing has a place. Medicine can work harmoniously with mental healing, and pain relief can help a person concentrate more fully on health. The private act of thinking perfect health is therefore offered as something available even when the body is suffering, but not as a substitute for necessary emergency care.

His interpretation of symptoms is equally distinctive. Physiology is said to create disease as feedback, signaling an imbalanced perspective or a failure to be loving and grateful. Within this logic, bodily signs are not simply terrible intrusions but messages about the person’s orientation. The book draws the further conclusion that love and gratitude can dissolve negativity in whatever form it takes, even presenting them as forces capable of dissolving disease.

Weight, Stress, and Emotional Orientation

Demartini’s teaching is applied to body weight through a direct challenge to the belief that food is responsible for weight gain. The book calls that belief unhelpful and argues instead that the thought that food causes weight gain is what gives food that causal power. Because thoughts are treated as the primary cause and physical outcomes as effects, the recommended mental correction is to think perfect thoughts, with perfect weight as the required result.

The definition of perfect weight is deliberately individualized. It is the weight that feels good to the person, not a standard imposed by anyone else’s opinion. This emphasis reinforces Demartini’s wider focus on internal orientation, though it also places the explanation of bodily condition overwhelmingly within personal thought.

Stress follows the same causal sequence. It begins with one unchecked negative thought, which generates further negative thoughts until stress manifests as an effect. Because the chain begins with a single thought, the book presents change as possible through one small positive thought followed by another. The body and emotional life thus become changeable fields rather than fixed verdicts: what has been manifested can be altered by changing the mental pattern that sustains it.

Narrative Role and Significance

Demartini gives The Secret an authoritative bridge between metaphysical language and therapeutic language. He speaks of frequencies, intention, and the creation of reality, but he also speaks through the recognizable institutions of chiropractic practice, medical knowledge, placebo research, and health consultation. This combination allows the book to present the law of attraction as both a spiritual principle and a practical account of why people experience particular states of health, debt, joy, or distress.

His role is also connected to the book’s recurring promise of freedom. Once thoughts and feelings are understood and mastered, people are said to see how they create their own reality; freedom and power are located in that mastery. The claim makes awareness a form of emancipation, but it also carries a severe burden of personal attribution, since suffering and disease can be read as reflections of mental imbalance. Demartini’s carefully stated acceptance of medicine moderates that burden in the medical sphere, while his emphasis on love, gratitude, and positive thought preserves the book’s larger promise that circumstances can be transformed.

As a featured co-author, he therefore helps organize the book’s central movement from unconscious repetition to conscious choice. His biography supplies a story of transformation, his psychology assigns thoughts a formative power, and his healing discourse turns the body into both evidence and messenger. Through him, The Secret’s promise is made concrete: change begins not with a different world imposed from outside, but with a different relation to thought, feeling, health, and the meaning assigned to present conditions.
