Jealousy as a Brain Illness: Why It Happens — the Method’s View

We usually treat jealousy as a personality trait or a “sign of love.” The method sees it differently: we must distinguish a natural stage of development from a state where the brain literally throws tormenting images at a person. This angle is about the mechanism — why jealousy arises at all, and where the line between norm and pathology lies.

Jealousy as a stage of personality development

A person is born without jealousy — they imitate everything, absorbing it from the mother. Until about age two, this concept simply does not exist for them. Jealousy is born when personality appears: the child responds to their name and begins to be aware of themselves.

“A person is born without jealousy. Until age two there is no such concept as jealousy at all.”

Year by year — two, three, four, five — jealousy grows, because the “I” grows: the person understands themselves and their environment more. This is a natural process of evolution, “set by nature’s price list.” Up to about 14–16 years, jealousy is normal. If development doesn’t stop there, it gradually dissolves by 18–21.

Where the line of normality runs

The method gives a clear marker: if jealousy appears or grows after 16–17, at 19, 20, 30 — this is no longer normal. It is either induced delusion or “something wrong with the neurons.” The older the person and the stronger the jealousy, the more it shifts toward psychosis.

The mechanism: a tired brain and a focused “I”

At the core lies the concept of the “I.” In a jealous person this mental concept is over-sharpened — they are fixated on it, they live by it. Everyone’s mood fluctuates: one way in the morning, another in the evening; in some, these swings are stronger.

When mood is low, the brain is tired, or the person takes toxic substances, everything “locks onto” this “I.” Then a depressive-paranoid state arises. The tired brain itself throws out a picture: “you’re needed by no one, you’ll fail, everyone looks at you like a degenerate.” A sense of real threat appears — paranoia — and the brain keeps replaying this picture.

The method distinguishes stages: a paranoiac state still keeps logic and a meaningful picture, while a paranoid one is already psychotic, more fragmented, where jealousy is purely delusional, with no connection or arguments.

A clinical example

A 48-year-old man complained that he couldn’t stop calling his wife — 250–300 times a day. His wife was 52 and ill with insulin-dependent diabetes. There was no basis for jealousy. But his brain constantly showed him images of betrayal, and these images tormented him so much that he called “to check, so it wouldn’t happen.” Meanwhile he worked as a train driver — hauling tanks of fuel through the mountains.

“Pictures. The brain shows pictures in front of me all the time… these pictures torment me so much that I keep calling to check.”

This shows the essence: a person suffering from jealousy is good — they simply have an ill brain.

The main takeaway

By definition, delusion does not yield to meaningful intervention — it’s useless to argue it away with words and reasoning. Help delivered head-on only worsens the state tactically, because the brain works differently. First the person must be brought back to normal, and only then — gently — can the mechanism be explained: “the child brain switched on,” it was an awkward cry for help.

“Never try to argue someone out of a delusion — by definition it does not yield to meaningful intervention.”

Practice: how to recognize the mechanism in yourself and others

1. Note the age and dynamics. If jealousy appears or intensifies after 16–17, that’s a signal it’s not norm but a brain state.
2. Watch the background. Fatigue, low mood, toxic substances — the soil the picture “locks” onto.
3. Recognize the “pictures.” Intrusive tormenting images and the inner dialogue “no one needs me” are the work of a tired brain, not facts.
4. Don’t argue with delusion. Persuasion and arguments are useless and tactically harmful.
5. State first, words later. Acceptance, support, physical closeness — and only when the person has “merged back into life” can you explain the mechanism.
