Astral Parasites: The History of Astral Larvae, the Belief, and What Feeling Drained Can Mean

Astral parasites, sometimes called astral larvae or “lyarvas”, are an esoteric belief about unseen entities that feed on human emotion. This article traces where the idea came from, from Roman ghost rites to Victorian Theosophy, and what research says about it. It also covers the real, checkable reasons a person can feel persistently drained.

What are astral parasites? The belief in brief

In modern esoteric writing, astral parasites are said to be non-physical beings that live on the “astral plane”. That is a plane of emotion and thought that many occult traditions describe as lying beside the physical world. Believers say these beings attach to a person’s aura and feed on heavy emotions such as fear, anger, envy and resentment.

Some writers add that habits such as overeating, smoking or heavy drinking feed them too. In this story, the parasite then nudges its host to repeat the emotion or habit, keeping its food supply flowing. The proposed remedy is to “raise your vibration” with sound, prayer, meditation, incense, scent and calmer emotions.

It is a vivid image, and it is worth understanding as a belief. It is not a medical or scientific concept. No study has ever detected such beings, and the word has no meaning in medicine.

Where the idea of astral parasites comes from

The belief did not appear from nowhere. It stitches together very old fears about restless spirits with 19th-century occult ideas about thought and emotion. Following the word “larva” shows how.

Roman ghosts: lemures and larvae

Ancient Romans feared the restless dead. They called them lemures, or more broadly manes, the spirits of ancestors. A smaller, nastier group were the larvae, described in some sources as mischievous or demonic spirits that troubled the living.

Every May, on the 9th, 11th and 13th, Romans held the Lemuria to keep these ghosts away. The poet Ovid gives the only detailed account in his Fasti, book 5. At midnight, the head of the house walked barefoot and washed his hands in spring water. He then threw black beans behind him for the ghosts to gather, saying nine times that with these beans he redeemed himself and his family.

The household then clashed bronze pots and called on the ghosts of their fathers to leave. Notice two details. Noise was used to drive spirits away, and the ritual was about protecting the family at home. Both themes return in modern “cleansing” advice.

From ghost to insect: what “larva” means

In Latin, larva meant “ghost, evil spirit, demon”, and also “mask”. English borrowed it in that ghostly sense in the 1630s. In 1768, the naturalist Linnaeus applied it to young insects that look nothing like their adult form. The insect meaning soon crowded out the spooky one.

That double meaning helps explain the modern image. “Astral larvae” sound both ghostly and parasitic, like grubs feeding on a host. The Russian form, lyarva, is where the spelling “lyarvas” in English-language posts comes from.

Victorian occultism and Theosophy

The 19th century revived the larvae in occult form. French occultist Éliphas Lévi wrote about larvae in his works on magic in the 1850s. The bigger influence was Theosophy, a movement founded in 1875 that blended Western occultism with ideas borrowed from Hindu and Buddhist thought.

In The Astral Plane (1895), Theosophist C. W. Leadbeater set out a detailed catalog of astral beings. He described “artificial elementals”, entities he believed strong deliberate thoughts and desires could create. He also described beings of “thirst and gluttony”, lust and cruelty.

Leadbeater wrote that these beings gathered around butchers’ shops and public houses, as pubs were then called. There, he claimed, they met living people with matching tastes and drained their vitality. He called them “minor vampires”. This is the clearest early version of the modern astral parasite story: entities drawn to vice, feeding on the people who indulge it.

Dion Fortune and “psychic self-defence”

In 1930, the British occultist Dion Fortune published Psychic Self-Defence. She argued that “psychic attack” and unconscious “parasitism” were more common than people realized. She listed signs such as dread, a weight on the chest, nightmares and nervous exhaustion.

Fortune also made a striking admission. She wrote that a psychic and a psychologist might sometimes be describing the same thing in different language. She warned that dispersing a supposed thought-form would not help if an underlying illness went untreated. Even within the tradition, then, some writers saw a link to the mind and to health.

Today’s version

Modern posts about astral parasites mix all these layers. The Roman fear of spirits, the Theosophical astral plane and Fortune’s psychic defense meet New Age language about “vibrations”. The result spreads widely on social media and wellness sites, usually with no sources at all.

Is there any evidence for astral parasites?

No. There is no scientific evidence that astral parasites, astral larvae or an astral plane exist. No instrument has detected an aura that could host them, and no controlled study has shown that such beings affect mood, energy or health.

Research on related practices points instead to suggestion. In 2001, psychologist Christopher French of Goldsmiths, University of London, ran a study with 80 people. Participants meditated while holding either a real quartz crystal or a glass fake. Both groups reported the same tingling and warmth, especially people who were told to expect it.

French concluded the sensations came from suggestion, not from the stones. That study was presented at a conference rather than published in a journal. Still, it illustrates a well-known effect: expecting to feel something makes people more likely to feel it.

Why the astral parasite story feels true to so many people

The appeal of the idea is easy to understand. It names something many people genuinely feel: being stuck in a loop of low mood, irritability, tiredness or habits they want to break. It gives that feeling a cause outside the self, and a clear plan to fight it.

The difficulty is that the “symptoms” in astral parasite writing match common, treatable health problems almost line by line. Compare the two columns below.

Left column: summarized from esoteric writing. Right column: from MedlinePlus, NIMH and SAMHSA. Only a clinician can tell which, if any, applies to you.

This is the real risk of the belief. If someone explains weeks of exhaustion as an astral parasite, they may burn sage instead of getting a blood test. Anemia or an underactive thyroid can then go untreated. The same goes for depression, which NIMH defines as symptoms most of the day, nearly every day, for at least two weeks.

How traditions say to “cleanse” astral parasites, and what we actually know

Many of the rituals recommended against astral parasites are old cultural practices with their own history. Some are pleasant and calming. None has been shown to remove an entity, because no entity has been shown to exist. Here is what each tradition teaches, what research says, and how to stay safe.

Sound: bells, singing bowls and chanting

Driving spirits away with noise is ancient; the Romans clashed bronze at the Lemuria. Many religions ring bells, and Tibetan Buddhist practice uses bowls, bells and chanted mantras such as Om Mani Padme Hum. Our guide to what a mantra is covers how chanting works within these traditions. More chants are in our mantra articles. Research on sound itself is limited. Treat chanting as a calming, meaningful practice, not a cure.

Meditation and mindful breathing

This is the one practice in the cleansing toolkit with meaningful research behind it, though not for anything astral. NCCIH summarizes analyses finding that mindfulness programs can ease anxiety and depression. A 2018 analysis of over 12,000 participants found they performed about as well as other evidence-based therapies. A 2019 analysis found mindfulness meditation improved sleep quality.

Meditation is generally low risk. A 2020 review found about 8% of participants had a negative effect, most often increased anxiety or low mood. NCCIH advises never using meditation to replace or delay medical care. For starting points, browse our yoga and breathing articles.

Smudging with sage and palo santo

Burning herbs to cleanse a space appears in many cultures. White sage (Salvia apiana) is sacred to several Indigenous peoples of California and the American Southwest. United Plant Savers warns that wild harvesting puts pressure on the plant, which grows only in southern California and northwestern Mexico. If you use it, choose cultivated sources.

Smoke is smoke. Avoid burning herbs indoors around babies, during pregnancy, or near anyone with asthma or other lung conditions. Never leave burning material unattended, and keep it away from pets.

Essential oils: frankincense, lavender, vetiver and others

Astral parasite posts often list oils said to “repel low vibrations”. That is a spiritual claim. The National Cancer Institute’s review of aromatherapy finds mixed results even for anxiety and sleep. Its safety notes are practical: don’t swallow oils, expect possible skin irritation with long contact, and avoid citrus oils on skin before sun exposure.

Pets need special care. Texas A&M veterinarians warn that many common oils are toxic to cats, including lavender, tea tree, eucalyptus, citrus, peppermint, rosemary and ylang ylang. Diffusing them where a cat can breathe the vapor is risky. See our oils and scents articles for the history of individual oils.

Crystals, visualization and prayer

Tourmaline, obsidian and amethyst are said in crystal lore to absorb negativity. As the Goldsmiths study showed, reported sensations from crystals matched those from glass fakes. Visualizing a protective light and praying for protection are spiritual practices that many people find comforting. They are personal choices, not treatments.

If you feel drained: a practical path that respects both belief and health

You don’t have to give up your spiritual practices to look after your health. The two can sit side by side. A calm evening chant and a doctor’s blood test are not in conflict. What matters is that rituals never replace a checkup.

Pay attention if the fear itself grows. NIMH lists early warning signs of psychosis, including growing suspicion, trouble telling what is real, withdrawing from people and sleeping much less. If beliefs about being watched or attached to start to frighten you, talk to a health professional. Do the same if they keep you from sleeping, working or seeing people. Early help leads to better recovery.

How to read astral parasite claims online

Search for astral parasites and you will find hundreds of near-identical posts. Many copy each other, and some sell cleansing kits, sprays or “removal” sessions. A few quick checks help you separate cultural history from marketing.

Reading the original texts is often more rewarding than reading the copies. Leadbeater’s The Astral Plane is free on Project Gutenberg. Ovid’s account of the Lemuria survives in his Fasti. Both show how people in very different times tried to make sense of fear, grief and unwanted habits.

Seen that way, the belief in astral parasites is part of a long human story. People have always looked for names for the heaviness they feel. Understanding that history can be meaningful. Looking after your sleep, mood and health is what actually helps you feel lighter.

Common mistakes with the astral parasite belief

1. Treating exhaustion as a spiritual problem only. Weeks of fatigue can come from anemia, thyroid disease, sleep apnea or depression, and all of these can be checked.
2. Blaming yourself for “low vibrations”. The belief can turn ordinary sadness or illness into a sense of personal failure. Feeling low is human, not a moral flaw.
3. Using rituals to replace support for addiction. Quitting alcohol or smoking is hard, and help works. SAMHSA’s helpline can point you to free or low-cost options.
4. Burning herbs around vulnerable lungs. Babies, pregnant women and people with asthma should stay away from smoke.
5. Diffusing oils around cats. Many popular oils are toxic to them, even as vapor.
6. Trusting unsourced posts. Most astral parasite content online cites nothing. Look for named authors, dates and sources.
