  • Cursed energy is a form of spiritual energy that leaks from humans as a result of their negative emotions, it makes up the bodies of cursed spirits, and it is used by jujutsu sorcerers and curses alike to fuel their jujutsu.▰▰▰▱▱ likely3 points

  • Curses are created when cursed energy leaks from non-sorcerer humans as a result of their harbouring of negative emotions. That energy gathers in one spot, building up like sediment and fermenting over time until a cursed spirit takes form.▰▰▰▱▱ likely4 points

  • Populated locations such as schools and hospitals are hotspots for bearing curses because many negative emotions are associated with memories of those places, and an image of fear shared by the masses can create a powerful curse even if the subject is not real.▰▰▰▱▱ likely2 points

    • Populated locations such as schools and hospitals are hotspots for bearing curses because many negative emotions are associated with memories of those places. This same concept applies humanity's collective fear and hatred. An image of fear shared by the masses can create a powerful curse even if the subject is not real, such as famous monsters or ghosts. It is the negative emotions that humanity directed at this image that causes it to manifest as a curse.Cursed Spirit - Jujutsu Kaisen Wiki analysis
    • The more negative feelings that surround a place or an idea, the more cursed energy fills that place or idea.Jujutsu Kaisen: 10 Confusing Things About Cursed Energy, Explained - CBR summary
  • Cursed energy and a cursed technique are not the same thing. Raw cursed energy can be used for its blunt force, but it is best used to power techniques in the same way electricity is best used to fuel electronics, with cursed techniques as the appliances that use that power to function. Soda cans are used as the example: cursed energy blasts the can, while a cursed technique concentrates that energy to twist it.▰▰▰▱▱ likely4 points

  • An innate domain is a mental landscape that embodies the mind of an individual, which jujutsu sorcerers, non-sorcerers and cursed spirits are all born with, and it serves as the foundation of a cursed technique. Domain Expansion uses a barrier to create a separate space where the innate domain is constructed with cursed energy and imbued with the user's innate technique.▰▰▰▱▱ likely3 points

  • The foreword to the Jujutsu Kaisen Official Fanbook states that, while World Trigger can provide detailed design and setting documents and Demon Slayer can provide meticulous notes on world-building, Jujutsu Kaisen does not have any of that.▰▰▱▱▱ likely1 source
    Supports
  • Cursed energy is described as the primary power source for any sorcerer or cursed spirit. Sorcerers voluntarily produce it, akin to the generation of electricity, and since negative emotions are the trigger, they train to create cursed energy from the slightest spark of emotion.▰▰▱▱▱ likely1 source

  • Other than cases where sorcerers die and become curses, sorcerers cannot give rise to curses. Cursed energy does not leak from sorcerers at nearly the same rate as non-sorcerers, because it flows heavily within them and stays contained, and in a general sense, if every human became a sorcerer it would be impossible for curses to exist.▰▰▱▱▱ likely2 points

    • Yuki informs Suguru that other than cases where sorcerers die and become curses, sorcerers cannot give rise to curses. Cursed energy does not leak from sorcerers at nearly the same rate as non-sorcerers. This is due to the difference in the amount of cursed energy sorcerers use and how it flows while being contained within their bodies. In a general sense, if every human became a sorcerer it would be impossible for curses to exist.Chapter 77 (Premature Death, Part 2) - Jujutsu Kaisen Wiki primary
    • This results in sorcerers leaking much less cursed energy than the average human. So much so, that if every human were a sorcerer, curses would cease to spawn. There are other differences in how sorcerers and non-sorcerers use cursed energy due to their profession, but the real reason lies in how it flows. While cursed energy leaks outward from non-sorcerers, it flows heavily within sorcerers which keeps it contained.Cursed Energy - Jujutsu Kaisen Wiki analysis

  • The English text of the manga is itself contested. A Chapter 226 line printed as a statement about cursed technique is listed among translation errors, with the correction given as a statement about Limitless.▰▰▱▱▱ likely3 points

  • Where cursed energy starts in the body is not put the same way in every source. One says cursed energy flows from the gut, with the brain directing reverse cursed technique. Another says most sorcerers instinctively believe it starts from the negative feelings in their stomach, that thinking of one's body as different sections is what delays the flow of their energy, and that one must realise they exist in the world with their entire mind, body and soul as one.▰▰▰▱▱ likely1 against3 points

    • Most sorcerers have to make cursed energy flow, so most instinctively believe it starts from the negative feelings in their stomach and flows through the rest of the body. However, thinking of one's body as different sections is what delays the flow of their energy. In order to understand this cycle, one must realize that they exist in the world with their entire mind, body, and soul as one.Cursed Energy - Jujutsu Kaisen Wiki analysis
